We commissioned a new RTEMS IOC here in Hawaii. The system ran for 2 days, 18 hours and 47 minutes before it simply halted. No exception was generated therefore no stack trace was seen. Also no console, no iocsh, no log messages. A system reset recovered our system before halting in the same manner 2 hours later. This occurred 4 times before the night ended. We speculate bad access or stack corruption but without a stack trace we're at a complete loss as to how to diagnose this. This same software release has run for several weeks at our other site with no issues. Is there a way to force an exception (or stack trace), for example with watchdog? Many thanks for your insight!
