Occasional random memory gobbling

It uses that much CPU when paused because the main loop is still running (it's not stopped waiting on select() - rather it's polling up to 100 times a second and going through the complete poll loop, even if the game objects aren't going anywhere fast).

The Mac version busy-waits when paused, too. Annoying on a variable-speed machine - my fan stays spun up when paused. This is what happens when you poll for input. ;-)

It's happening quite a lot for me (linux 1.62-2).

I usually see it after big battles (when it's most annoying!), but I just had the same problem while fuel-scooping from the sun. I'd checked the memory usage not long before and it was fine.

The hyperspace trick worked, it actually deallocated all of the memory it had gobbled so far.

Sounds like the AI is the culprit, then. Well, that's my hunch (the AI is something which can cause memory allocation to happen - obviously it's not a classic memory leak since the memory does get freed when you hyperspace). But hyperspacing away will clear the AI's state.

Does the AI state remain after docking? I've had at least one occasion where this glitch has occured while docked.

Perhaps I'm seeing this problem more often because I only have 256mb on my machine at the moment... but then again I've been running ut2004 without these problems.

Yes. When you’re docked the simulation is still running and other ships are flying about out there.

What?!? You mean when I hide under the blankets they DON'T go away? Waah!!!

I think this is what makes Oolite cooler than the average bear - the fact that life goes on whilst you are in the docking bay.

It also saves a lot of time on relaunching, seeing as you are not having to reload the 3D universe everytime. It also makes it easier for the developer(s), since the universe carries on moving at its own rate, meaning that anything could be happening out there.
