[Gluster-users] gluster connection interrupted during transfer

[Raghavendra Gowdappa]

Normally client logs will give a clue on why the disconnections are
happening (ping-timeout, wrong port etc). Can you look into client logs to
figure out what's happening? If you can't find anything, can you send
across client logs?
