Description:
Bug ID 722657: Mcpd and bigd monitor states are getting out-of-sync intermittently ... Last Modified: May 14, 2024 ... Severity: 3-Major ... Symptoms ...

Impact ... -- False monitor status in UI/CLI. -- Large number of RST connections as traffic is directed to a pool member that is actually DOWN ... Conditions ... -- Monitor is attached to pool member and bigd does not inform the state change event for a long time in some of the corner cases. -- No periodic events from bigd to mcpd. ... Workaround
