The vmcore file was sent to Epoch (the people who wrote the Epoch Software that
drives our Optical Jukebox. They suggested that we run the olds_post_install
(OnLine Disk Suite) program to fix up some incompatibilites between ODS and
the Epoch Kernal changes. Hopefully this will fix the problem..

It means your kernel is failing to allocate memory.

A backtrace would be of more interest - that would tell us more about what
the system was doing when this failed.

My suspicion is that you have a third party optical scsi disk driver that
is having a bad day. I don't recall an osd.c amongst the kernel source
that comes to do kernel builds in generic...

In the source code for this particular file there is an ASSERT()
function call. If this call returns false then the message is printed
and the system is halted because something happened that wasn't
supposed to. The file in question is in th edirectory relative to where
the kernel was built, ie /sys/sun4m/OPTICAL1/../generic/osd.c.

My guess is that this is the driver for the optical scsi disk, so you
should contact the vendor who sold you th eunit and report the panic to

Note that the source file may not be on your system, there might only
be an osd.o which is th ecompiled object.
