Subject Channel full exception
Date Tue, 21 Apr 2015 07:06:06 GMT
Hi , 
I am using the flume JMS source to dequeue message from ActiveMQ and convert this message
into `List<Event>` using custom converter
Channel configuration
    agent.channels.c1.type = memory    agent.channels.c1.capacity = 1000000    agent.channels.c1.transactionCapacity
= 1500
when size of the `List<Event>` is less than or equal to 1500 (channel transaction capacity),then
flume write the events to channel , but if the event size is greater than 1500 then  i am
getting the below exception
