Hello!
Something wicked happened to my server tonight, it suddenly locked up after 60 days uptime. I was running 2.4.32-grsec.

I then reset the machine and now everything seems back to normal...
Any ideas what might be causing this?

Without more information, the only thing I can suggest is to upgrade to 2.1.8.
Did you notice anything before the crash occurred? Was memory usage unusually high?

Hello!
Sorry, i don't know quite what information would be useful...
I was using grsec 2.1.7 of course, as the kernel was compiled back in november.
Here is a graph from cacti that shows the memory usage. At 1:30 am the box locked up, at about 2:30 i reset the machine.
It seems something went wrong with the memory, but i can't tell what and why... http://www.musichat.net/porcodio.png

parce-que je ne suis pas un francais fanatique... pour Ãªtre precis, je ne suis pas fraincais du tout... et spender je crois quand-mÃªme.
et btw, ou est ton problÃ¨me... l'anglais est la langue universelle du internet, si je veux parler en francais je vais aux moulin rouge, pas dans le forum de grsecurity.
