Hi Christian,

The failure indicates to me a problem in your code, because it should not happen.  The failure is happening in pasynManager->lockPort().  Is your code calling that function explicitly?  

Is the failure reproducible?

Is this on Linux?  If so, you can generate a core file and run gdb on it to get a traceback.

Subject: mutex lock assertion failure

Hello,

I encountered the following assertion failure in one of our IOCs. Is this EPICS-internal, or something  that can originate from our own code?
