Okay, listen up folks. I've proven this successfully three times now.
I can disconnect and then get the reconnect list back (all disconnected instances and "New") for twenty-three instances. (I haven't manually tried to reconnected them. I'm assuming I can once they are listed.)
On the twenty-fourth disconnect, Logic hangs. VE Pro does not crash, only Logic.
I Force Quit Logic. The remaining three instances are still listed as "connected localhost" in the 64-bit server window. When I re-launch the song file in Logic, the previous twenty-three instances successfully re-connect (automatically, as the Logic song loads). Then Logic loads three new instances, ignoring the three that are still listed as "connected localhost" in the server window.
Perhaps this goes unreported because no one has yet disconnected and attempted to reconnect this many instances on a single computer. I'm only doing it to diagnose regrettable CPU performance linked to a high template load on a single computer.
EDIT: Hi Karel. I'll try to send you something soon, now that I know how to invoke the crash.
