Hello.
I'm having a Solr running within Tomcat7 and Tomcat is closing at
fixed hours, everytime is a different hour. catalina.log doesn't show
anything other than a clean tomcat shutdown (no exception or
anything). I would really apreciate some advice on how to debug this.
Tomcat doesn't run anything other than solr.
The Context XML definition for the solr application is the following:
<Context path="/solr" docBase="/opt/solr/webapp">
<Environment name="solr/home" type="java.lang.String"
value="/opt/solr/solr-home/" override="true"/>
</Context>
Here are some relevant messages from catalina.log:
