PCIE Fatal Err: Critical Event sensor, bus fatal error (Bus 0 Device 0 Function 0) was asserted
1. The error message can be found in http://support.dell.com/support/edocs/software/smdrac3/idrac/idrac1.11/en/ug/html/chap13.htm, it indicates "Fatal error is detected on the PCIE bus."
2. If you ran application with unsupported PMU event(s), sampling will report it then stop.
3. Can you run same amount of events with smaller application? Can you run small amount of events with bigger application?
4. 40-50 events are too much for one sampling activity. Sampling will separate these events into several sampling sessions. I don't know if there is the problem - if sampling stops one session, and terminates bigger application...quickly another sampling session invokes bigger application again.
My suggestion is to separateone sampling activity (with 40-50 events) into several sampling activities (with a few events).
