Dear Folks, We are using Solr 5.4.0 - "stand-alone" mode in our production boxes hosted in Red Hat Enterprise Linux (RHEL) OS.
Each box have number of different cores. Have attached the screenshot shot with the Solr core & system details. 1. Earlier indexing was performed every 30 minutes in both production servers, 2. In linux-a server 30 (stand-alone) cores created on same day and content indexed into it, 3. we then spotted unusual GC performing every 2 to 7 seconds in linux-a server and the Solr process spiked, 4. Then we removed the indexing in linux-a server for a week, monitored the both Solr process and GC.(No indexing performed during this time), 5. No one uses the system during night time which we ensured it from our end. But both Solr process and GC were in its peak, even "during non business hours", 6. Have restated Solr instance in linux-a server. GC started again after Solr instance brought up, 7. In linux-b server no spike in Solr process and no issues with GC, We couldn't figure out why Solr process is hight and GC performing frequently in linux-a server. Have anyone encountered similar issue? Can anyone help to suggest on ways to spot the issue please ? Regards, Thirukumaran M
