Experimental Physics and Industrial Control System
Hi all,
It is the second time I got the same issue on one of my IOCs and I'm not
sure how to debug it, as it happens randomly (twice in 3 months, each
one one a different instance of the same IOC). When this issue happens
the PVs from my IOC becomes unavailable and I got this message on the
IOC prompt:
A call to 'assert(status == epicsMutexLockOK)'
by thread 'PDB-event' failed in ../freeList/freeListLib.c line 143.
Dumping a stack trace of thread 'PDB-event':

When the issue happen I still can use the IOC prompt.
I haven't seen this issue with previous base version.
Thanks in advance
Cheers
