Frequent kernel panic

[lemonz]

Hello,
First sorry if writing in wrong section.

I'm a very happy user of PVE and PBS and I love them!

This because in the last ca. 2 months, my PBS install is going in kernel panic randomly...
I've already checked much logs as i can and i can't find nothing usefull...
I'm keeping updated my pbs install as much as i can (maybe i'm doing wrong?)
Disks and hardware are healthy
How can i investigate better on this?
If needed, my hardware is this:

i5-4460 on a MSI H81M-P33
2x 4GB DDR3 + 8 GB swap
250 GB SSD + 2x 1TB RAID1

What is shown in SYSLOG and/or on Screen when kernel panic happens?

Thanks for reply.
In /var/syslog i don't see nothing usefull, since file starts on today when i rebooted the server (i had to hard-reboot it because even keyboard wasn't working)
but i see that in /var/log/kern.log.1 errors which was shown on monitor attached to the server
I'll attach it here

Yes, dates are correct, the server has been running in kernel panic since July 13th because I wasn't at home to reboot it physically

Well, check your RAM. (Memtest)

Uhm, okay thanks, i'll do it as soon as i can (probably this saturday),
Do you think is the ram?
Ah, i don't know if can help, but just for completeness, in this istance i'm backupping around 20 vms/cts, and some of that multiple times a day (every 6 hours)
Can it be also excessive load for PBS?

Anyway, thanks for you help!
