Hi Guys,

Thanks so much for the comments.

I believe I have a local issue here that is not related to any of the community software.  I added the epicsExit(0) call to the IOC's that are in areaDetector, and then began receiving errors with these on exit also.  A second Windows box was then configured (on a different network), and it did not show the same symptoms.  Also, Mark Rivers' did not see errors on exit with the areaDetector IOC's with the epicsExit(0) added in.

Fresh install time.! :)

Thanks again.

Best Regards,

Mark Clift.

Thanks to Lewis for pointing our that the areaDetector main programs were not calling epicsExit(0).  They should have been, and that was causing a problem on Linux, where typing exit would NOT exit, it would hang.  The only way to kill the IOC was to type ^C.

I just added the epicsExit(0) call, and it fixes that problem on Linux.  I also checked that it does not introduce the problem Mark Clift is seeing on win32-x86, those IOCs continue to exit cleanly with no errors.  I am building everything statically on both win32-x86 and linux-x86.

Mark

Another possible difference is that the areaDetector IOCs don't invoke
epicsExit before returning from their main function; other IOCs do.
