: : 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.
this doesn't appear to be related to Solr. You can see from your logs that the command originats from outside of solr -- I suspect you would see the same problem if you ran a tomcat instance on this port w/o using solr at all. My guess is you have a rogue cron command either running on the local machine or using the remote shutdown port telling tomcat to shutdown. (perhaps it's looking for tomcat ports whose logs suggest they aren't getting a lot of traffic? or aren't registered with a load balancer?) You might want to start by making sure you have remote shutdown support disabled... https://tomcat.apache.org/tomcat-7.0-doc/security-howto.html#Server ...and checking the crontab on the local machine to see what runs on the hour. -Hoss
