Hi there,

We have two nodes running graylog-server (v 1.2.0) and ElasticSearch in both of
them and I'm trying to figure out what happened that forced us to manually
cycle the deflector in order to see our messages again. We are processing a few
hundred messages per second, running with 3.5GB heap in the ES JVMs & 1.5GB in
the graylog-server JVMs.

I can see the following (somewhat filtered) in the graylog logs, in the
ElasticSearch logs I only see JVM GC duration WARNings. On a side note, I'd be
great to have some ERROR log yelling about messages being lost (or at least,
nowehere to be found).
