We're bring up EPICS 3.14.8.2 on VxWorks for a Xilinx VirtexII FPGA with a PPC405 core and are having intermittent problems that I thought someone might recognize.

To keep it simple we are only loading the dbExample dbs (although we've increased the scan rates to .1 second). We are also running about 10 Probe clients.

We see the following on the VxWorks console:

program
Exception current instruction address: 0x01e32680
Machine Status Register: 0x00029200
Condition Register: 0x20000044
Task: 0x1e32770 "CAS-event"
filename="../../../src/libCom/taskwd/taskwd.c" line number=174
task 0x1e32770 suspended

I tried the 'tt' command as recommended in the archives and see:

> tt 0x1e32770
12d290 vxTaskEntry    +64 : 1037844 (f28bcc, 1e9cc58)
10378c0 epicsThreadOnceOsd+174: f28bcc (1e9cc58)
f28e3c db_post_single_event+758: f2876c (1e9cc58)
value = 0 = 0x0

Of course it's intermittent and hard to reproduce.
