This is one possibility. It is also possible that your sink is not
keeping up with your source. If It can't take items out faster than the
source can put them in, events will pile up and the channel will fill up.

You could try increasing the channel capacity. Add the following to your config

host1.channels.memoryChannel.capacity = 500

Subject: Channel Exception
Hello,
I am trying to send the events to the Avro Source through external RPC client..
While sending the events, the following error is thrown
org.apache.flume.ChannelException: Space for commit to queue couldn't be
acquired Sinks are likely not keeping up with sources, or the buffer size is
too tight

I have also changed the heap size to 1024m
And my host file is as follows:
host1.sources = avroSource
host1.channels = memoryChannel
host1.sinks = esper
#avroSource configuration
host1.sources.avroSource.type = avro
host1.sources.avroSource.bind = localhost
host1.sources.avroSource.port = 41414
host1.sources.avroSource.channels = memoryChannel
#Channels
host1.channels.memoryChannel.type = memory
#Sinks
host1.sinks.esper.type = com.gsshop.bigdata.poc.flume.EsperSink
host1.sinks.esper.channel = memoryChannel
What could be the reason for this error?
Regards,
SOm
