> 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.
