SOLR Cloud: Few cores goes to recovery mode all of a sudden
Hi,
We are using 3 node SOLR (7.0.1) cloud setup 1 node zookeeper ensemble.
Each system has 16CPUs, 90GB RAM (14GB HEAP), 130 cores (3 replicas NRT)
with index size ranging from 700MB to 20GB.
autoCommit - 10 minutes once
softCommit - 30 Sec Once
We are facing the following problems in recent times
============================================================================================
1. Few Indexes goes to recovery mode without any prior error or warnings

What could be the reason how can we avoid such failures in future?
How can we fix "AlreadyClosedException" without restarting the service.
Thanks,
Doss.

Posted by Doss <it...@gmail.com>.
Thanks Erick,
ulimit in all three lodes are more than 65K including max process list. If
you look at the timestamp the core down error happened ahead of unable to
create thread error, and also core down error took place in node1 and
unable to create thread error took place in node3.
BTW we are running the SOLR instances in VMs. We are maintaining only last
three days zookeeper logs.
Thanks,
Doss.

Re: SOLR Cloud: Few cores goes to recovery mode all of a sudden
Posted by Erick Erickson <er...@gmail.com>.
The “unable to create new thread” is where I’d focus first. It means you’re running out of some system resources and it’s quite possible that your other problems are arising from that root cause.
What are you “ulimit” settings? the number of file handles and processes should be set to 65k at least.
Best,
Erick
