Mohit Anchlia created FLUME-1850:
------------------------------------
Summary: 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.
