Hi,

In currently available logs I think disconnect logs are coming in brick_logs is
expected. It seems on the nodes cli command "gluster v heal info" running
continuously 

I have tried to search client logs related to pid "30292" as logs shared in
comment 1 but i did not find any log specific to this client.

find ./ -type f | xargs grep -il "PID:30292"
./father/glusterfs/bricks/wall-pool-brick.log-20180826
./father/glusterfs/bricks/wall-pool-brick.log
./spirit/glusterfs/bricks/wall-pool-brick.log-20180826
./spirit/glusterfs/bricks/wall-pool-brick.log
./son/glusterfs/bricks/wall-pool-brick.log-20180826
./son/glusterfs/bricks/wall-pool-brick.log

I have tried to find the client logs for pid 23095 

find ./ -type f | xargs grep -il "PID:23095"
./father/glusterfs/bricks/wall-pool-brick.log-20180826
./father/glusterfs/bricks/wall-pool-brick.log
./spirit/glusterfs/bricks/wall-pool-brick.log-20180826
./spirit/glusterfs/bricks/wall-pool-brick.log
./son/glusterfs/glfsheal-pool.log
./son/glusterfs/bricks/wall-pool-brick.log-20180826
./son/glusterfs/bricks/wall-pool-brick.log

and I have found below messages

client_logs(glfsheal)
