RE: startPVAServer prevents windows-x64 IOC from exiting

Hi Michael,

Thanks for pointing out that startPVAServer is no longer required.  When I remove that line from commonPlugins.cmd in ADCore things work fine.  The PVA server still runs, and I no longer have the problem with IOC exit hanging on windows-x64 and windows-x64-debug.

It is interesting that having the unneeded startPVAServer does not cause problems on Linux or windows-x64-static, only on dynamic windows builds.

Thanks,
Mark

That is interesting.  You should not need startPVAServer.
The PVA server starts automatically during iocInit(), and has done so for some years.

Running startPVAServer again should be ok though.  Only
printing:

However, I guess you have found a logic error.  Perhaps with the ordering?  You might try reversing the order of these two statements.
