Overheating glitch?

[yorshee]

I've seen this bug before but 1) It's never happened to me before and 2) I thought it got fixed in 1.0.4.

Once I got this craft into orbit, everything starts overheating, starting near the fairing/docking port and it spreads to everything else over time. If I let the connection between the command pod and the fairing explode and separate, it stops, but of course I don't want that. I had to use the debug menu just to get this screenshot.

The very first thing that starts overheating is the short Rockomax adapter, if that has anything to do with anything. The large nuclear engine has nothing to do with it, there's nothing active under the fairing either. The heat spread speeds up with the fairings deployed. If I let the adapter explode, the fairing piece cools down over time, whereas the small parts attached to the command pod remain a consistent temperature where the heat gauge is half-full, and the radiators do nothing to dissipate it.

Has anyone figured out what causes this, and how to fix it? Even the radiators do nothing. If you need any more information, like the parts of the ship or a video of it in action, then I will be happy to provide it. If you think the output logs will help then I can post those too, it's just that the debug log in the debug menu shows nothing out of the ordinary.

I had this problem when using the 64 bit hack. Which version of KSP are you running?

OsX, Linux (32/64) or windows (32/64)?

[yorshee]

I'm using Windows, and the 32-bit version of the game.

I saw in the other overheating glitch thread that it's caused by FAR but this isn't the cause of it for me because I don't have it.

Same reports here: http://forum.kerbalspaceprogram.com/threads/126664-MAJOR-Heating-Bug

Happened for me today with a brand new ship, x32, Steam version. My faulty part is a SAS-module; tears my station around the Mun in half. It seems to be a pretty common bug. No solution yet, as far as I know.

One thing I found that helped a little was offsetting parts that may be clipping into other parts a bit. I offset the adapter out of the fairing base so no part of the adapter model was touching the fairing base and it stopped it....temporarily. It happened again, but once I was near Moho's orbit. I knew it probably wasn't the Sun because the heat spread was happening insanely quickly (this happens when the fairings are deployed, which they were) and I wasn't firing any engines. It's very odd...

I'm going to try to recreate this with 100% stock parts.

EDIT: It happened again with a different ship made of stock parts, this time a decoupler kept overheating and exploded. I think it may have either something to do with service bays or heatshields since that's what is near the adapter on my first ship, and near the decoupler on the ship I made just now.

I have this issue with a large SAS unit, others with batteries, stuff inside fairings or struts. It isn't related to a particular part or mod.

A fix, at least for me: http://forum.kerbalspaceprogram.com/threads/126664-MAJOR-Heating-Bug/page4

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.

My minmus space station had parts overheating and exploding. I found out that the radiators store heat while in the sun and transfers this heat to other parts and makes them explode. Only use radiators while using equipment and keep an eye out for rising temperatures. Don't leave radiators open while not using them for anything or they will transfer radiation from space all throughout your ship and make it overheat and explode.

I figured out a different cause of my problem.
