I have a Cassandra node that is going down frequently with 'java.lang.OutOfMemoryError: unable to create new native thread". Its a 16GB VM out of which 4GB is set as Xmx and there are no other process running on the VM. I have about 300 clients connecting to this node on an average. I have no indication from vmstats/SAR that my VM has used more memory or is memory hungry. Doesn't indicate a memory issue to me. Appreciate any pointers to this. System Specs: 2CPU16GBRHEL 6.2
Thank you.
