Hi Daniel,
I don’t think the error below is related to the crash.
The SOLR error below is probably happening because you have upgraded your xwiki instance
and haven’t removed/cleared the SOLR index. We mentioned this in the release notes since
we changed the SOLR index format recently.
See http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWiki53#HSolrS… for
example.
On the crash aspect you should check the memory usage when it crashes (you can take a heap
dump on OOM for example).
Thanks
-Vincent

Hi all,
I am having a problem with XWiki that is driving me crazy. It periodically
crashes--interval between crashes from a few days to a few weeks. There
are no errors in the log when it happens.
I am running XWiki enterprise 5.4.2 on Ubuntu, using Tomcat7, Postgresql,
and LDAP authentication.
I am getting errors like the following every hour in the log. I don't know
if this is related or not:
