The problem you describe isn’t specific to pcaspy, it’s the general behavior when you have multiple CA servers on the same computer.

Read 
https://wiki-ext.aps.anl.gov/epics/index.php/How_to_Configure_Channel_Access
which describes "Multiple IOCs on the same computer”, note that it mentions "only the IOC started last will actually receive UDP search requests” and gives several ways to solve this.

I don't know how to solve the problems. Thanks.
