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.
