Sep 09, 2019

Known Affected Releases
Symptom: The RSCN or ZONE service crashes with the following syslog message: %SYSMGR-2-SERVICE_CRASHED: Service "rscn" (PID 5405) hasn't caught signal 11 (core will be saved). or %SYSMGR-2-SERVICE_CRASHED: Service "zone" (PID 5430) hasn't caught signal 6 (core will be saved) MDS 9700 can incur a switchover, however in most cases, the crash occurs again before the standby is available and the dual supervisor switch will reload. For Example: <pre> `show system reset-reason` ----- reset reason for Supervisor-module 5 (from Supervisor in slot 5) --- 1) At 161169 usecs after Thu Dec dd hh:mm:ss 2014 Reason: Reset triggered due to HA policy of Reset Service: rscn hap reset ... ----- reset reason for Supervisor-module 6 (from Supervisor in slot 6) --- 1) At 422003 usecs after Thu Dec dd hh:mm:ss 2014 Reason: Reset triggered due to HA policy of Reset Service: rscn hap reset </pre> Conditions: This issue occurs only when 'port' format RSCNs are configured and an RSCN is sent on the relevant VSAN. RSCNs are sent, for example, after activating zoneset changes or a link changing state. Further, only the following platforms are affected: MDS 9710 MDS 9706 Nexus 7000 Nexus 7710 This issue does not occur when RSCNs are sent with 'fabric' format.
