I found the cause of the crash.
The problem was calling epicsThreadSetPriority from a thread not
created via epicsThreadCreate.
I committed the change and a change to epicsThreadTest.cpp to test
epicsThreadSetPriority.
When I run epicsMessageQueueTestHost on solaris it never terminates
but does do everthing it should???
Is this the same issue that I reported on Nov 11th for Linux-x86? (See
attachment.)
No. It was the issue Earnest raised.
For the problem shown below, I am not sure we can guarantee a fix. The
test keeps creating threads until it fails. At this point it is not
clear what state the underlying operating system is in.

3.14.8@Linux: epicsMaxThreadsHost does not return

On my Linux (Debian 3.1; gcc 3.3.5) box:
epicsMaxThreadsHost does not return properly. In most cases it runs
almost complete

then hangs at this point, probably in a system call (doesn't recognize
control chars, has to be killed explicitly with -9).
In other cases, the outputs stops /before/ the "number threads" line
with the same behaviour.
In the hanging state, 'ps' shows zillions of threads, which I would
consider normal during that test.
I'm aware that this could be rather a Linux configuration problem than
really related (or even caused) by the test from base. Nevertheless:
Any hint about where I should look further?
