Hello All,
I systematically get this error when I restart MCF after running a job
that uses a new Repo Connector I'm creating:
ERROR 2025-03-03T13:01:30Z (Agents thread) -
MCF|MCF-agent|apache.manifoldcf.agents|Exception tossed: Service 'A' of
type 'AGENT_org.apache.manifoldcf.crawler.system.CrawlerAgent' is
already active

This error runs in a loop, even after restarting the service again. I
have to stop MCF and wait a while, maybe ten minutes, then restart MCF
again and the error disappears. I have found a workaround: change the
parameter: "-Dorg.apache.manifoldcf.processid=A" to "B" for example. I
switch between "A" and "B" to restart MCF.
I've been careful to close all my connections to any remote services I
might use, and these closures work fine... I've cleared everything in
the disconnect() method of the Repository class. No matter how much I
compare my connector with others that don't have this problem, I can't
see any big difference with what I've done...
Have any of you ever faced this error?
