Description (partial)

Symptom:
The zone service crashes (due to some other defect, eg CSCvu16159) while processing an inband FC zone command, for example a SFEZ or GFEZ command. However, the zone service has lost information after the first crash and is an unrecoverable state. This causes further crashes, this time due to signal 11. This defect is about the signall 11 crashes.

The following syslogs may be seen:
<pre>
%SYSMGR-2-SERVICE_CRASHED: Service "zone" (PID 31551) hasn't caught signal 11 (core will be saved).
%SYSMGR-2-SERVICE_CRASHED: Service "zone" (PID 5469) hasn't caught signal 11 (core will be saved).
%SYSMGR-2-SERVICE_CRASHED: Service "zone" (PID 12374) hasn't caught signal 11 (core will be saved).</pre>

This causes the switch to reload.

Conditions:
This issue applies to all MDS platforms. It occurs after a zone service crash occurs while processing an inband FC zone command.
