Experimental Physics and
Industrial Control System

I have downloaded EPICS base 3.14.7 and built it under the provided 'hpux-parisc' setting of $EPICS_HOST_ARC. All built fine. I built a test client program that performs a couple channel access fetches and prints the results. The test program works fine when I build against our existing EPICS 3.13.2 installation, but there is a problem running with the newer EPICS version. The program performs the channels access operations correctly, but the signal value prints are sometimes followed by "epicsThreadOnceOsd epicsMutexLock failed" written to the command shell. I suspect the message is generated when I close the channel and exit the program. The number of times the message is written varies from zero to two. More often it is zero, and only once have I seen two. Can anyone explain to me what this message means, and what I need to do to correct it?
