Not as far as I know. APS DAQ software does not use startPVAServer. We have a wrapper singleton class (https://git.aps.anl.gov/C2/daq/modules/daq-base/-/blob/master/src/pva/DaqPvaServer.cpp?ref_type=heads) which starts PVA server whenever the first instantiated plugin acquires singleton instance and adds its PVA record.

Yes it does.

He did.

It is mentioned in the " Adding QSRV to your IOC" section of the QSRV1 documentation.
