Is this a new instalation?

Have you done any kind of customization or deployed any new addon or something like that?

Hi Douglas,

thank you for your reply.

It's a relatively fresh install of Community - 5.2.0 (re21f2be5-b22) with an Apache proxy. It's not customized except for a different favicon and a logo on the top-left. However, I installed some addons:

Ezuno AddOn (Desktop Client)
Site-Creators AddOn

It's a good hint to start there, thanks a lot. When there's time to, I'll disable them to see if one is the cause.

I see.

Those addons/changes should not cause you any problems.

One thing you can try is to reindex your repository.

Did a reindex according to Performing a full reindex with Solr | Alfresco Documentation . Exception is still there. Curiously the log did not contain such messages mentioned in the help documentation ("Creating new index"). However, the files were re-created and search works, although still the first query after every Alfresco restart is extremely slow (waited quite a while before testing, so reindexing should already have been completed). All succeeding queries run at good speed.

I had a look at the solr monitoring console, but could not spot any obvious problems. Everything looks ok.

This is a known issue with SOLR 1 logging in 5.x after an upgrade of the slf4j library.

SOLR 1 is deprecated and only supported for upgrade in 5.2. You should be using SOLR 4 or search services.

It is most likely you have SOLR 1 installed but you are not using it.

Andy,

thanks for your reply. You were right, the exception was indeed caused by solr1. It was gone after removing all solr1 components:

<alfhome>/tomcat/webapps/solr
<alfhome>/tomcat/conf/Catalina/localhost/solr.xml
<alfhome>/alf_data/solr
