Re: Flume is replaying log for hours now
I use 3.5G but I can change it to 5G.

Not sure I understand what you mean about dual checkpoint, this is my
configuration for each of the three channels, should I change it?

collector.channels.mc1.type = file
collector.channels.mc1.checkpointDir=/home/flume/collector1/channels/mc1/checkpoint
collector.channels.mc1.dataDirs=/home/flume/collector1/channels/mc1/data
collector.channels.mc1.capacity=100000000
collector.channels.mc1.transactionCapacity=10000
collector.channels.mc1.use-fast-replay=true
