Hello Chris,

Referring to Mantis 259:

The first question to ask is what might be different between this and a more
conventional PPC. Is it a site specific vxWorks BSP?

It says "Exception current instruction address". Do we know what type of
exception it is (this presumably can be decoded from the machine status
register value)? Could it be a floating point exception? Are the floating
point registers saved by ISR that use floating point?

Does this happen only if CA clients are connected?

You might also try the following:

O Use the "i" command to see if any of the TCBs (task control blocks) are
corrupted and or if any other threads are suspended (in a failed state).

O Use the memShow command to detect corrupted pool. 

Jeff
