I got the following on both my test and prod server. The error also
shows up in simple history:
Error: KeeperErrorCode = NoNode for
/org.apache.manifoldcf.locks-_Cache_OUTPUTCONNECTION_Solr/read-0001039554
I guess it is related to the shutdown process - either when I stopped
the Resin instance or the Agent. Just mentioning.
BTW, for some reason I had to restart the job on our test server. Our
prod server hangs at the moment, so I will try to restart everything
once again. The applied patch works well, but version 1.7.1 seems to be
tricky. I'll publish a thread dump and my logs if I'm not manage to run
MCF on our prod server until I leave office.
This is what I can see in manifoldcf.log:

Please vote on whether to release Apache ManifoldCF 1.7.1, RC0.
This release fixes a number of critical issues, as well as a number of user
priorities, most notably:
- A bad Zookeeper support issue, which made locking support fail when
Zookeeper connections got lost and then restored;
- The Alfresco connector, which was nonfunctional in both MCF 1.6 and 1.7;
- Solr Cloud support, which had ceased working due to changes to SolrJ;
- Non-null connector components caused failure;
- PostgreSQL queries not performing well.
The complete list of included fixes can be found at:
