[OmniOS-discuss] Tips on diagnosing an OmniOS lockup?

[Matthew Lagoe]

I would run memtest on the system I have had similar issues in the past with
bad ram/cpu/mobo

Doesn't sound like a OS issue tbh

Subject: [OmniOS-discuss] Tips on diagnosing an OmniOS lockup?

 We have a situation where one of our OmniOS NFS fileservers (running
r151010 although not current on updates) is hanging/locking up mysteriously
(other identical servers run fine). No messages are logged either to the
console or to syslog and the machine becomes almost totally unresponsive; at
best it pings, but input on the console is ignored and network services
(including NFS) no longer respond.

 Beyond 'use mdb -K so we can capture a crash dump the next time this
happens', do people have any suggestions for diagnosing the cause here?

 Thanks in advance.

PS: if people want to know the hardware and setup details, this and
    its links are a description of the systems:

    The fileserver systems are not currently using the LSI SAS ports for
    anything so I believe we should be unaffected by any OmniOS issues
    there.
