Symptom: Getting below error messages RP/0/RSP0/CPU0:Feb 20 07:42:29.000 : statsd_manager_g: %MGBL-IFSTATS-4-COLLECTOR_TIMEOUT : A stats collector has timed out during a request: Node 0/0/CPU0, PID 462942 RP/0/RSP0/CPU0:Feb 20 07:46:09.000 : statsd_manager_g: %MGBL-IFSTATS-4-COLLECTOR_TIMEOUT : A stats collector has timed out during a request: Node 0/3/CPU0, PID 462942 Conditions: with very large scale, subscriber churn is happening and at same time we execute command "show l2vpn.. ", we see time out. In code, these codepaths do share a mutex lock.If subscriber delete/create path acquires mutex first Then ?show l2vpn ..? cli might have to wait until the other thread releases the lock which introduces Latency potentially resulting in this timeout.
