Everything is overheating and exploding!

[Just Jim]

OK, I'm not one to start screaming bug, but I've already read some other people here are having problems with stuff exploding, and now 2 of my space stations have also gone boom. Something is either very wrong, or maybe it's a lack of the new radiator parts, but everything is glowing red hot, and in the case of the space stations, white hot

I turned on Debug and set ignore max temp, and engaged the temp overlay to get this screenshot. The second I turned ignore max temp off it exploded. It started with one solar panel that kept getting hotter and hotter, and spread to the upper half of the station.

When I checked my other ships and stations, they're also all glowing red, and I expect a couple to also explode soon.

I don't know what's going on, if it's a bug, or if ships need the new radiator parts to stay cooled off. I actually hope it's just a bug. If I need to relaunch a bunch of ships with new radiators that's gonna set my game back bad!

Really not sure what to do here, I have a considerably expensive space station thats very unusable now and I'd like to know what I can do to fix it. If anyone has any fixes, I'd love the help!

Edit: Not sure what is causing this, I tried detaching the part that originally overheated and the rest of the ship remains hot, not sure what this means the issue is

Hope i doesn't get these heat problems with the OKS station from UZI colonization i'm going to build in my new science save (don't like carrier).

[thereigo]

The station I have is completely unusable, everything I dock with it becomes infinitely overheated, even if I detach it from the station. Really annoying, I'm not sure how to fix this.

So far, with just a few random experiments and doing things, it does seem like using small parts with masses LESS than 0.01 in symmetry, especially in cargo bays, seems to make things heat up and go boom. Only certain parts seem to be more prone to this than others. The cargo bay just speeds up the process somehow. When same parts are not in a clamshell, they don't heat up until later or when deployed in space. I've tested batteries, solar panels, lights, etc. For instance, a small camera from one of my mods is totally fine for 10+ launches/missions. On a random part of any of those missions, it may become the root cause of heat startings. Another mission, the parachute may become the cause. I wonder if it has anything to do with the amount of small mass objects attached to a ship. Quantum struts also overheat randomly. The good thing is that I can revert to a quicksave and it may or may not happen again even if doing the exact same actions that led up to the time of overheat. Maybe someone who has time and more knowledge can piece everything together and find the root of the problem.

Edit:
Parts that overheat will eventually read this after letting them go or warping 1-50x:
Thermal Mass: 298
Skin T.Mass: 6.2
Temp: Infinity
Skin Temp: Infinity
Cond Flux: NaN
Conv Flux: -Infinity
Rad Flux: -Infinity
Int Flux: 0.00
SkinToInt Flux: 3.66

Time warping on launchpad cures the heat problem during warp and brings temps down to a more normal range when warping 1000x. SkinToInt Flux moves around while bringing up warp.

Finally a fix:

Początkowo opublikowane przez Starwaster:

Set conduction factor to 1. (Alt-F12 -> Physics -> Thermal -> Set Conduction Factor slider)

If that cools things down for you then gradually increase Conduction Factor, stopping before things get uncomfortable. (or just leave it at 1)

Note however that reentries will become more dangerous because skin heat will leak through at a slower rate. (that is in fact one of my tricks in the latest Deadly Reentry)

Setting Conduction to 1 WORKED! No more crazy overheating out of the blue. I did some maneuvers, placed the station in another orbit, did some science, EVA's and set back the conduction to the default value of 20.000, and nothing exploded or overheated.
Many thanks! Me and my Kerbonauts are forever grateful! Danger averted.

That's the temporary workaround I use to keep the game playable. Struts, batteries, solar panels, small objects (mass?), struts, decouplers, symmetry, and alignment to rotation of Kerbin all play a part to this heating issue. Any one of these things can cause the heat to get out of hand and blow parts up within a split second.

Just tried setting my Conduction to 1 (well, slider wouldn't land right on one but I tried just over and just under) and my station didn't cool down, thanks for the advice though. Any other possible work-arounds?

[Xyster]

You'll have to do this every time you re-start your game. Make multiple quicksaves and use the quicksave option (f5) often. When you come back into atmosphere from orbit, you may want to set it back to 3+ or the ship may burn up. You could also just tick "ignore max temp" at the start of every game too until this gets fixed.

Have you tried warping time after setting it to 1? Also, after that, return to space center, go on EVA, modify the orbit slightly etc. I found that such actions help prevent another overheat after setting conduction factor again to 20 000.

[thereigo]

Tried warping, EVA, Space Center, Adjusting Orbit, all with Conduction Set to 1. Unfortunately, nothing so far

Just tested it out on my other smaller spare computer. Overheats on stock game still. Fresh install of both Windows AND KSP. It doesn't appear to be with only tiny objects. Any satellite (large or small) with certain different random configurations seems to trigger the spike in heat. Cond Flux starts negative and skyrockets parks 3k+. Other temp attributes like Rad Flux etc also change. Turning off Cond Flux brings temps back down. Lowering Cond Flux to a smaller number, such as 2 or 3, will slow the heat somewhat, but not cure the problem. I have to move parts around on the satellite randomly to get it to not overheat. Parts overheat that have symmetry and the are aligned in the same direction. Changing the parts or rotating them around without snap seems to cure the heat problem SOMETIMES.

Also, when bugged parts are thrown into a fairing, the fairing's Thermal Mass is around 1500+.

The problem reported on this bug tracker for an overheating service bay is pretty similar if not identical. I made a mistake by overlooking/dismissing it earlier since I thought it was only related to service bay deployment.

Hopefully this helps anyone else work around this issue and continue enjoying playing the game as much as I do.

Going to have to put this game back on hold again for a bit. Afte starting over and trying to work around the random heating of smaller parts and the seperate issue of weird cond. flux in cargo bay that causes explosions due to heat, I am now getting a bug that I thought was patched already. Jumping out of warp with all temperatures of ship perfectly fine, the craft suddenly heats up within half a second and pops. Too frustrating to keep trying to work around these issues and/or loading quicksaves over and over due to bugs when I usually wouldn't need a quicksave at all. :(

As reference, someone else recently had posted this problem on the forums: http://forum.kerbalspaceprogram.com/threads/126747-1-0-4-battery-bank-exploding-in-space-due-to-overheating-after-SHORT-bursts

Has anyone figured out the root cause of this issue? Is it a bad equation somewhere with the new heat system? I've been looking everywhere for an answer and have only come across quite a few posts on forums and of people having this same issue. I haven't seen any official posts as to what the problem could be or how to work around it for the time being. If there was a way to strip the new heat system from the current build, that would work for me.

Seems to be also the same issue

If you are using any designs made before 1.0.4 it will have serious problems. And the occasional bug still pops up here and there.

But the heating stuff is mostly due to older designs. You have to trash em all. To save a career you have to trash all your ships and be prepared to cheat to bring people home.

After that though, so long as you make new designs, and using radiators its fairly relaible.

[grandnovice]

Fresh install of game, but new or old designs?

[Xyster]

Fresh everything. Fresh career, fresh designs, fresh drive install, and even tried with a different computer. Overheats occur with certain designs sometimes consistently. On stock game, with ignore max heat ticked, heat builds in certain parts (usually symmetrical), and the cond./conv./rad flux all fluctuate wildly to infinity. Max time warp stops the heat, but returns as soon as time warp slows. Changing sliders only delays the heatings and allows to see which parts are overheating. Cond. Flux and other numbers jump from negative numbers to positive and spiral to infinity eventually.
