Hello Everyone,


A weird issue occurred yesterday. I'm using 4.2.f CE on Centos in production and it has been working for over a year with no issues.

Suddenly I'm getting this error message in the logs.

09:42:00,015 ERROR [org.quartz.core.ErrorLogger] Job (DEFAULT.org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean#34367433 threw an exception.

I thought that the indexes were corrupt so I followed the documentation to reindex. That gave no positive results.

I then went to a previous night full backup and restore content and database and I'm still getting the same error.

What the outcome of this is that in /share it still works, but the search functionality and also tags are not working.

I can search users (which I think is done differently), but I cannot search content. When I go to the tag manager it gives the same error.

Does anyone have any ideas of what I can do? My only solution is to reinstall Alfresco and then use my backup/database, but I'm afraid if go through all that trouble I'll still end up back where I am right now.

Solved:

Turns out that there were some solr core files that were some how deleted in the alfresco install.

/install/tomcat/webapps/solr

After copying the contents of that directory over to the production install and starting the service again. Everything is kosher.

Not sure how the files got deleted though….That is still a mystery.
