Hi Jeffrey and Ralph,

I am observing occasional/intermittent error in the vxWorks EPICS IOC. Error occurs during connection from CA client to the PVs in the IOC.

mvme6100 IOC is running on EPICS version 7.0.6.1. We have CA clients using Java JCA library 2.4.1 and pyepics 3.5.0.

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

by thread 'CAS-client' failed in ../db/dbEvent.c line 540.

EPICS Release EPICS R7.0.6.1.

Local time is 2022-09-06 14:58:32.719904388 CST/CDT

Please E-mail this message to the author or to tech-talk at aps.anl.gov

Calling epicsThreadSuspendSelf()

Do you have any insights on how to avoid this error?

Thank you,

Oleg Makarov and Mark Hillgart
