Dear Ralph,

         I observe  some errors on   IOC  while exit from the IOC shell with exit command.

 

 

 

 

A call to 'assert(status == epicsMutexLockOK)'

    by thread 'CAS-client' failed in ../../../src/ioc/db/dbEvent.c line 490.

[      0x3817ee8b5d]: /lib64/libc.so.6(clone+0x6d)

EPICS Release EPICS R3.15.0.2 $$Date$$.

^C

[screen is terminating]

• rsrv is shutting down one of its CAS client threads (TCP handler). While removing all subscriptions of that client, being inside db_event_disable() it finds the lockset mutex went away (line 490 of dbEvent.c).
• The log client tries to send a message to the log server, and finds the client mutex went away (line 241 of logClient.c).
  errlogGetSevEnumString+0x24a is errlogThread(), the call to logSendClient() is via *plistenerNod->listener (line 577 of errlog.c).
