I don't see any errors/warning with DEBUG.
Here is the problem: if I tried to read a line larger than 2.5 MB and send via memory channel, the sink lost it and won't receive anything afterwards.
Here is the configuration I tried:
Source: exec. I tried both cat/tail command, and a Java program to read lines from file and print to stdout.
Channel: memory channel and file channel. I think capacity of memory channel is about the size of the queue of events, which won't affect the max size of an event.
Sink: both HDFS and Fill-Roll. They are able to receive short events before large events come.
Can you suggest what to configure? I'm using Flume 1.2.

This depends on your memory configuration. When you start flume with DEBUG did you got some errors / warning?
