More info please.

Was this during a game or after it ended?

What type of game? (quick, training, online, etc)

What map / theme / mode / settings were used?

Do you have a log (My Documents/Hedgewars/Logs ) and or demo of that game?

Thanks in advance.

I was sitting in the menu, which is weird because I'm pretty sure hwengine only starts when you go into a game. I was suddenly notified my computer had to shut down photoshop due to low ram availability.

My guess is I failed to close hedgewars properly at some point, and sitting overnight the hwengine ram file grew to a massive file size due to, perhaps, some sort of memory leak. This is all speculation, though. As for the logs, I don't see anything relevant in them relating to any error, maybe because they've been overwritten since I've had tons of games since then.

Hum I see, thanks for letting us know anyway

It would be awesome if you maybe could always check the task manager after each game (regardless of being player or spectator) for us, so that you maybe catch hwengine not closing properly again and then can tell us what kind of game it was/etc. and how you left/quit it.

I'm asking this because it's hard to reproduce the issue for us.
But it has been reported before and is definitely a thing that bothers people.
So gathering any information about what circumstances lead to hwengine not shutting down properly would be greatly appreciated.

If that's too much of a hassle for you that's cool too though, don't worry

PS: hwengine should indeed only be running while in-game or while generating a map preview.
So your theory of a game not shutting down properly and hanging around in the background all night seems spot on.

I have no idea what could have caused this leak, but wondering if possibly accidentally triggered video recording of something super-long could be the reason.

I also had the same issue back when I was playing on windows.
The hwengine process would not be killed after a game is finished.
In this occasion the hwengine would go crazy after some time.

Can you confirm that you were playing a round before this happened?

I'm really inclined to blame video recording in your case as well, Anachron. The r key is awfully easy to hit accidentally. You might want to check vids portion of hedgewars if you see this happen again.

I've encountered a pulseaudio shutdown problem in tye past, but it left a blank game window open which neither of you are mentioning. The things that run in background are previews and vid generation. Video seems the most likely.

No, if that was the case I'd have demos in my C:\Users\Admin1\Documents\Hedgewars\Demos folder, I don't. I haven't been able to replicate it, but I know it has happened in the past. I think it's related to a bad termination of the program.

Nope, there were no movies inside C:\Users\\Documents\Hedgewars\Videos afaik.
Just FYI, I couldn't find a use for screen recording (I use a different program) so I disabled the recording.

Plus iirc it will display an information ingame if I activate screen recording, which also did not appear.

I play with a controller and don't chat. I didn't even know you could. T never struck me to be a talk key, if anything i'd figure it was Enter.

So, I accidentally triggered video recording yesterday, for just a few seconds.
I halted with r.

I came back today and noticed hwengine chewing up tons of CPU even after a game.

Seems to be stuck in this STOPVIDEORECORDING

Ended up kill -9ing the process.
