Hi Everyone,
We are seeing continual OOM exceptions on one of our 1.1.0 elasticsearch
clusters, the index is ~30GB, quite small. I'm trying to work out the root
cause via heap dump analysis, but not having a lot of luck. I don't want to
include a bunch of unnecessary info, but the stacktrace we're seeing is
pasted below. Has anyone seen this before? I've been using the cluster
stats and node stats APIs to try and find a smoking gun, but I'm not seeing
anything that looks out of the ordinary.
Any ideas?
