Hi Mike,  How do you know what client is requesting those names? My guess is it may be a sequence program (or maybe a PV named in an access security file) running on the same IOC which hasn't been given the right prefix.

The 'dbcar' command lists the IOC's dbCa links, and can confirm or deny that it's a database link (use dbcar "*", 0/1/2 to see increasing amounts of info). You'll need to use the sequencer commands seqShow and seqChanShow to check for unconnected channels for your sequence programs, I forget what the arguments are to seqChanShow but I think you give it a program name and "-" to see only disconnected channels. There is also a similar 'ascar <level>' command for reporting CA connections if you're using access security.

HTH,

- Andrew
