Access Fault

["Dennis M. Reichhold" <reichhol@rcf.rhic.bnl.gov>]

Hello-

     I'm running version 3.12.2 on a 167.  The program is relatively
simple; it just reads out a stream of data from some Allen-Bradley
modules.  It had been running stably a few months ago.  I just turned the
processor back on yesterday, and within five minutes, I got the following
Access Fault message:

Access Fault
Program Counter: 0x0008c91e
Status Register: 0x3009
Access Address : 0x01010101
Special Status : 0x0505
Task: 0x78a990 "tNetTask"

after which, all channel access is lost.  Every time I reboot, I
eventually get this message, sometimes with "(CA event): panic: mget"
messages beforehand, sometimes not.  Can anyone help me with this?  
Thanks.
