That is interesting.  When it is hung and you type

epicsMutexShowAll, 1

repeatedly, do you always see the same thing, i.e.

> ellCount(&mutexList) 117 ellCount(&freeList) 12
> epicsMutexId 0x894b988 source ../../asyn/asynDriver/asynManager.c line 1868
> epicsMutexId 0x89a2710 source ../../../src/libCom/osi/epicsMutex.cpp line 222

No.

I ran it with one record.  Hung (with same mutex report) after less than
two hours.
