After some more investigations (due to a third crash, and my server unvaillibility) I found something new in the log :
In the same time as all the crashes, I have in my apache2 access.log a lot of concurrent access from the same IP (I think from a bad configured corporate proxy) This may be the root cause -- "Smbd","kjournald2" and "rsync" blocked for more than 120 seconds while using ext4. https://bugs.launchpad.net/bugs/494476 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
