--------------------------------------
I was able to generate the zip from live instance that just now threw memory
error but upload is just taking forever.
> OutOfMemory Error

> Key: FLUME-1850
> URL: https://issues.apache.org/jira/browse/FLUME-1850
> Project: Flume
> Issue Type: Bug
> Components: Node
> Affects Versions: v1.3.0
> Environment: RHEL 6
> Reporter: Mohit Anchlia
>
> We are using flume-1.3.0. After flume is up for a while (30 days+) we get
> OutOfMemory error. Our heap is set to 2G and load on the system is very low.
> Around 50 request/minute. We use AvroClient and long lived connection.
> Below is the stack trace. I don't have the heap dump but I plan to enable
> that for next time.
