Hello to all,

I'm having some problems with OpenNebula since version 3.4.0. The machine
is freezing after a a fews days, normally a week, it stops responding to
pings, ssh sessions although it still keeps the VMs running and Sunstone
operational (probably in memory, didn't tested it yet). The only solution
to this is rebooting the machine, but it is very annoying and also I get
the XFS disk corrupted sometimes and have to run a repair for several hours.

In the kernel logs, nothing very relevant, apart from XFS mount fails I
filtered this:

Jun 20 10:10:38 cloudpt qemu-kvm: Could not find keytab file:
/etc/qemu/krb5.tab: No such file or directory
Jun 22 11:26:05 cloudpt mcelog: Cannot open logfile /var/log/mcelog:
Permission denied
Jun 22 11:26:05 cloudpt mcelog: failed to prefill DIMM database from DMI
Jun 22 11:26:05 cloudpt mcelog: Cannot bind to client unix socket
`/var/run/mcelog-client': Permission denied
Jun 22 11:26:10 cloudpt setroubleshoot: SELinux is preventing
/usr/sbin/mcelog from write access on the directory /var/run. For complete
SELinux messages. run sealert -l 6be2b6bf-e51a-4cb7-a01c-fc867ecb902b

I'm running SL6.2 on the machine, and from 3.0 and 3.4 there were no OS
changes or updates. Any ideas?
