We just experienced a bizarre occurrence with our beamline vme crate.
Suddenly, it started to spontaneously reboot over and over, each time
giving the message "WorkQ Panic. kernel work queue overflow", near the end
of the process of loading all our databases, etc.  This continued until we
turned the crate off. I would appreciate any info about where this might
come from and/or how to test if conditions are leading to this state.

We recently switched to an mv162 from an mv167, but are running the same
application we have run for quite awhile, with the exception of version 3.4
of the motor record and device support. Another difference is that I was
getting an error when the crate booted about a missing device support entry
table for an unused motor controller because of a makefile error (since
corrected).

We are running epics 3.13beta11, and vxWorks 5.2.1
Thanks very much.
