4-STABLE server crashing

Hello.
As per subject, a 4.11 server of mine started crashing quite often; I
upgraded it to 4-STABLE just in case, but this didn't solve.
I'm attaching three backtraces; can someone give me any hint?
I'm oviously willing to provide any further needed info.
I also checked to see whether the hardware is ok and I think it is,
although I might obviously be wrong.
bye & Thanks
av.
