For the past couple of weeks, my client has just unexpectedly close, it doesn't stop responding it just closes itself, there's no particular pattern to how long it will take from opening the client.

My FPS is fine (around 52 usually) there are no connectivity problems as I can easily connect to all rooms and memory usage is normal.

Im using v4.92. (through steam)

I have a 2.5Ghz quadcore processor and a radeon graphics card, both of which can cope with higher graphics and higher moemory games, I have 6GB of RAM

Any ideas are welcome, thanks

This has also happened to me many times.
As suddenly as it appeared, it disappeared.
For me restarting Toribash/PC made it better.
For me I had a slight pattern, it was when someone loaded a sparring/parkour mod or when I tried to chat, sometimes it was 100% random.

For me its completely random, sometimes its even when im tabbed out of the client

Two things that might help finding out what's happening are crash.txt and stderr.txt, both in your toribash folder. Check them out or paste 'em here (preferably in [code][/code] tags).

I was unable to find the crash.txt file - there are however a lot of mdmp files with the word crash in them, might not be relevant but might as well mention them

the stderr.txt file was empty

I think you have got a missing file or something that is broken, I would recommend reinstalling the whole game.
It could also have been that you have a program that is causing the problem, so I would 2nd recommend looking through your computers all programs and see if there are any you do not reconize or use, if you find something then delete it.
If you are on the steam-version you can right-click a Steam game and go to the properties. Look for Verify Integrity of Game Cache under Local Files. It should scan your install and make sure everything is there, and if not it will get what it needs from Steam.

I have tried reinstalling it.

When I verified the integrity of game cache, it said 1 file failed to validate and will be reacquired. This may be one of the files Jtank mentioned(?) but im not sure. I will post again if it appears to have worked and close the thread

If it does not work, then try doing it again and restart your computer after it is done.

It appears to have worked, I will leave this thread open because I cant be sure yet, but I will close it if I feel sure

EDIT: Nope it happened again

Does it happen even if you launch toribash and open singleplayer, then don't move anything? Try checking it.

In the meantime, as a workaround you could try using a different version of tb, here's link with list that has 4.8 or 4.82, you can probably google for news thread with 4.9, 4.91, 4.92
