There is a memory leak in ASM control plane daemons after processing many calls in a long lived process
Memory consumption by ASM control plane daemons increases.
A) Pool member state changes frequently. or B) Manual learning is enabled (versions 12.x)
Restart ASM - which will cause a failover and a down time OR just kill asm_config_server by: ----------------------- pkill -f asm_config_server ----------------------- which will get restarted back by ASM process watchdog in ~15 seconds and should not cause failover nor downtime.
An async worker lifecycle was introduced so long lived processes will now dispatch a fixed number of calls to their workers before retiring them.
