Hi Dave,
Thank you for the reply. We are using the below config for usergrid:
m4.xlarge EC2 instance
Ubuntu 14.04 (HVM)
4.5 GB RAM is dedicated to TOMCAT (heap memory)
Oracle JDK 1.8.0_65
Please note, Cassandra + ES runs on a separate/different EC2 instance.
Thanks for the help.

I think things have improved in the (hopefully) soon to be released v2.1.1,
but I cannot say for sure that we have eliminated OOM exceptions.
Somebody might be able to offer some advice if you can tell more about your
setup: what kind of computer (or what AWS instance type), how much total
RAM and what Java VM heap settings (and other) are you using.

Hi Dave,
We also noticed that the Tomcat/Usergrid process runs out of memory (Java
Out of Memory exceptions).
Has this issue been fixed/resolved in any recent/new version of Usergrid.
Please advise.
Thanks

I've seen this happen on some Usergrid instances in the past and I think it
happens because these types of things:
- The Tomcat/Usergrid process has run out of memory, i.e. Java Out of
Memory exceptions
- Usergrid has lost connectivity to Cassandra and the Cassandra client
(Hector or Astyanax) gets into a bad state
But those are just my guesses about the problem.
Check your logs for exceptions that might be helpful in diagnosing the
problem.
Thanks,
Dave
