Description (partial)

CE-7 Degraded by core file,On June 1st at 22:44:33 PANG restarted with core dump.
The cause of the SW restart is a general protection signal.
Jun 1 22:44:33 ce-7 kernel: pang[24020] general protection ip:a27bec sp:7fe97e415c40 error:0 in pang[400000+7ff000]
While the cache application was writing the core dump, it got a reboot command from the leader, for not functioning in the past 5 minutes. Due to the reboot the core dump is incomplete (truncated).

BFD: Warning: /opt/pang/bin/core.25048 is truncated: expected core file size >= 21729755136, found: 15150313472.

Detailed root cause analysis:  Not enough data to determine root cause, it requires getting the complete core dump which matches with the partial core dump as above.   Final root cause indeterminate based on lack of data.
