I went ahead and made a ticket for this. Locally I made a bandaid fix:
Connection_Manager.First (ID);
while ID /= 0 loop
begin
Close (ID);
Connection_Manager.Next (ID);
exception
when others =>
Connection_Manager.First(ID); -- restart if cursor is deleted early
end;
end loop;
It isn't a good long term solution probably, but I tested it with multiple
connections up and didn't seen any glaring issues. I"m sure it breaks
something though. It can potentially call Close() on the same ID twice, if
the exception occurs a few iterations down the line. I don't know if that
is bad or not. I also don't know if the same fix will work for the
Watchdog version of this bug (the one that pings all the IDs). Starting
over there could be costly?
