ApplePMU::PMU FORCED SHUTDOWN, CAUSE = -93 - thoughts?



Hello!

Since the beginning of the fall term here, my xServe has spontaneously paniced/restarted 4 times: Aug 26, Sep 1, Sep 22 and today (Sep 27) with the same thing in the panic log:


Tue Sep 27 10:39:49 2005
panic(cpu 0 caller 0x000E6D70): vnode_put(3523294): iocount < 1
Latest stack backtrace for cpu 0:

0x00000000
Proceeding back via exception chain:

Kernel version:
Darwin Kernel Version 8.2.0: Fri Jun 24 17:46:54 PDT 2005; root:xnu-792.2.4.obj~3/RELEASE_PPC



and this in the system.log:

Sep 27 10:39:47 localhost kernel[0]: ApplePMU::PMU FORCED SHUTDOWN, CAUSE = -93


I've made no real changes to my server (apart from installing whatever is coming through Software Update) within this past month and my *AFP* use of my server has been very consistent. My SMB use of my server has probably increased with the return of the students here.



I'm looking for some advice as to what might be causing these recent panics or what other log information I could dig up that might be something I could track that would show what's going on.


Thanks!

- Steve
