9967.0. "vm_object_free 3.2g" by NNTPD::"[email protected]" (Adrian Morrisson) Wed May 28 1997 06:37

Hi
	I've got a crash that has a panic string of
 _panic_string:  0xfffffc00005a5a58 = "vm_object_free: res count > 1"
The OS is 3.2G and I've tried canasta with no results.
There are no related HW errors in uerf
There are messages in /var/adm/messages or the syslog files about / being full
 but there are in the crash file so I assume root is full due to the crash

The system is an 8400 5/440 Quad CPU 2GB memory running DU3.2G fully patched
        with the DUV32GAS00001-19970314 
I'm only attaching the relavent parts if the crash
Any Clues, more info?

We have seen this before and are investigating.  You should file a CLD/IPMT
so that we can give you some debug code to try.
