startPVAServer prevents windows-x64 IOC from exiting

[Mark Rivers via Core-talk <core-talk at aps.anl.gov>]

I previously sent this message to both tech-talk and core-talk.  Neither Andrew Johnson nor I received it.  I know that some people who are subscribed to tech-talk did receive it.  It looks like perhaps people who are subscribed to both lists do not receive the message at all?

 

I the future I will only send to one list or the other, since Andrew points out that core-talk is a subset of tech-talk.

Folks,

 

I have found a serious problem with using the PVA server on Windows IOCs that are dynamically built.  The IOC runs fine, but cannot be exited either with the “exit” command or with ^C.  It can only be killed with the Windows Task Manager.  The problem occurs on the following:

 

• EPICS_HOST_ARCH: window-x64, windows-x64-debug.  Does not occur on windows-x64-static.
• EPICS BASE: 7.0.7 and 7.0.8.  Did not test other versions.
• Test application: makeBaseApp.pl from base 7.0.8.  Modified st.cmd to add the line startPVAServer just before iocInit.  Also happens in ADSimDetector with commonPlugins.cmd.

 

Thanks,

Mark
