Tracking communication timed out

Question asked by knightrider on Sep 8, 2015
Hi!
I was deleting a large folder using the REST API. It was working properly and then I got an error (see below). Since then i get the following errors in catalina.out and solr.log :
[solr.tracker.CoreTracker] [SolrTrackerScheduler_Worker-3] Tracking communication timed out

I tried restarting the alfresco service with no success. I thought it could be a problem with the indexes so I deleted them so the system would rebuild them when restarting, but same error occurs…
What can I do to fix this ? I have no idea what to do ?

Here is an extract of my catalina.out file when my delete started to fail :
