Solr error "trackers work was rolled back by another tracker error"

Jump to solution

Currently the solr failed, we had initial error in solr.log

2019-02-01 15:19:38,051 ERROR [org.alfresco.solr.tracker.AbstractTracker] Tracking failed

And then followed another, which constantly repeated periodically since then

Besides we had warnings in alfresco.log at the same time, which are also repeated since then

After alfresco service  restart, the error has gone. So the problem may be considered as solved.
