Bhavik Patel commented on RANGER-4147:
--------------------------------------
[~madhan]
However, higher memory requirement, of 40gb, doesn't seem right
==> right, we did some enhancements at HDFS and now our kms server
consumes only 14gb.
I will see if I can attach the access log by EOW.

# have you checked if KMS service is getting rebooted when client got timeout?
==> No KMS service is not rebooted.
# Are you getting heap dump when KMS is crashing, due to
-XX:+HeapDumpOnOutOfMemoryError. ==>
## We haven’t seen KMS were getting crashed.
## we did some enhancement at HDFS end and after that we haven’t OOM(OOM we
observed initially only)
# Thread dumps when load is high. ==> It's our production environment so we
are not allowed to take dumps.
# CPU usage, how you are finding CPU load. Is it "top" command ? ==> yes,
thanks for the clarification.
