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
