Game crashes once or twice a match

[FoldingChair]

Hi Guys

I'm running Ubuntu 10.10 on a Q6600 / 4GB Machine with a Nvidia 9800 GTX+

For quite some time now HoN keeps crashing predictably once or twice a match.
If I Alt+Tab to some other Program (e.g. a Browser) in the beginning of a match I can nearly be sure of a crash. Otherwise the game runs for some time but will then crash.
I attached two crash.logs iirc they are from the same match (from Saturday).
As it says something about a Segmentation Fault and the nvidia Driver:
I'm running the up to date proprietary nvidia driver available from ubuntu. I'm not sure which version it is, but I'm willing to try nvidia-current-dev if you think that might help.

Also on a related (?) topic I recently had a graphics bug when looking at Myrmidon at the end of the game (no problems in the beginning). When I screenshot it, the game crashed, as soon as the Ubuntu "Where do you want to save the screenshot" Window popped up. http://img220.imageshack.us/img220/8788/myrmidongraphicsbug.png

Thank you for any suggestions!

You should use game's interface to save screenshots, not the OS one. Also please try the newest drievrs you mentioned, and try the older ones you had before.

Update your drivers, you are running 260.19.06 (buggy-as, esp with pthreads) 260.19.29 are alot better - would cause a segfault.

Also gfx tearing is usually a sign of a thermal issue, could you check your cooling

Do you know if you are using prelink?

OK, even though it took me quite some time here my results:
I queried the temperature of my gpu every 30 seconds while gaming

nvidia-smi -q | grep Gpu
and it didn't get above 65° C which should be perfectly fine.

Also I updated the nvidia driver to 270.18. Sadly that didn't help either. My game still crashes to Desktop every now and then. This happens more often if I Alt+Tab to Firefox or any other program.

I don't know if I use prelink, but I guess I could try to find out if you told me how.

Thanks for your help!

what is hte output of mount | grep tmp

[FoldingChair]

sudo mount | grep tmp
none on /dev type devtmpfs (rw,mode=0755)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
truecrypt on /tmp/.truecrypt_aux_mnt1 type fuse.truecrypt (rw,nosuid,nodev,allow_other)
That is without HoN started, but it didn't seem to change when I checked with HoN started.
