Hello,
i had some serious trouble with stability in the last time. Sometimes my
box freezes and was not leaving any log messages in /var/log but
yesterday, when i was trying to commit a few changes to my local
repository, i got some strange error messages from subversion, followed
by a complete freezed computer :(
After i was rebooting, i found this error message in /var/log/kern.log

>From now on, every time i try to do execute "svnadmin recover" (to
recover the repository) or "svnadmin create", the system freezes. I am
not able to start any new programms, nor can i save open files to the
harddisk, but i am able to execute some simple commands like ls and i
can edit opened files in vi. If i execute "svnadmin create" for the
second time, the system totaly freezes and i am unable to anything, only
hit the reboot button.
Executing "fsck.reiser4 --check /dev/sda2" (my root partition) just
tells me that everything is fine.
Kind regards
