My server is randomly locking up hard on RC4. IPMI reset not working so i have to power cycle.

This problem is causing parity checks which are taking a bunch of time and are returning all ok. So at lease that's some good news. I'm attaching diagnostics and here is the last piece of the syslog I collected prior to the crash... (I'm using a raspberry Pi as a syslog server)

It looks like everything goes pear shaped at Mar 31 14:00:06

 

Any help is much appreciated. My feeling is that this is RC4 related, since RC3 didn't pose any issues for me.....

Cheers
Steve
