Hello,

for two weeks I get every day
Code:
Kernel Panic - not syncing: Fatal machine check on currend CPU
Pid: 59, comm: kswapd0 veid: 0 Tainted: C M ...2.6.32-19-pve
Call Trace:

In the /var/log/syslog there are a lot off errors like

Code:
Apr 18 22:14:43 proxmox01 pmxcfs[1629]: [status] notice: RRDC update error/var/lib/rrdcached/db/pve2-storage/proxmox01/backups: -1
Apr 18 22:14:43 proxmox01 pmxcfs[1629]: [status] notice: RRD update error
/var/lib/rrdcached/db/pve2-storage/proxmox01/backups:
/var/lib/rrdcached/db/pve2-storage/proxmox01/backups: illegal attempt to update
using time 1366316083 when last update time is 1366317428 (minimum one second
step)
Apr 18 22:14:43 proxmox01 pmxcfs[1629]: [status] notice: RRDC update error
/var/lib/rrdcached/db/pve2-storage/proxmox01/backup: -1
and so on....

I see that the ntp is not working proberly
Now I have reconfigured ntp
The RRD errors and the Kernel Panic are away since 24 hours
and the Proxmox Server works normally again
Code:
Apr 19 13:21:15 proxmox01 rrdcached[1619]: flushing old valuesApr 19 13:21:15 proxmox01 rrdcached[1619]: rotating journals

Apr 19 13:24:53 proxmox01 pvedaemon[53016]: <root@pam> successful auth for user 'root@pam'

My question:
Can the kernel panic caused by the wrong time be?
Or is a possible connection between kernel panic, RRD (C) and the wrong time(NTP)?
