Package: kernel
Severity: important

My system (RHEL 5.4 KVM guest) got unaccessible (*very* high cpu load). After rebooting it and checking the logs, I found out that a kernel issue appears:

I have been running a backup script which bzips some important files to a WebDAV server today, but it had been working flawlessly a few times before.

This is not a kernel bug.  Your WebDAV server appears to be storing the
entire file in memory, and VM guests generally do not have swap space.
You should consider increasing the memory size for this guest.
