For development and testing, I sometimes have to run multiple agents on the same server / workstation. Recently I had to load test a second agent in a Windows environment with a near identical configuration (except for paths and more memory allocated to the JVM), but the agent in the second JVM soon ground to a halt whereas the first JVM with less memory worked without slowdown.
The total physicsl memory on the machine is 32 gb, and the total physical RAM used never exceds 14GB. Disk space is plentiful. Agent A (started first) has a max JVM heap space of 4 gb, the second JVM (Agent B) has 8 gb allocated. Both use a spooling file source, a memory channel, and an Avro sink. Yet agent B is the one that slows down and evetually hangs. I have stood up multiple Flume agents on Linux without this problem. What could account for the degrading performance in a Windows environment for the second agent but not the first? All the best, Chris p.s. The agent version is 1.3.0, and I can't change it for contractual reasons.
