Description of problem:

Currently glusterd is crashing when enable/disable heal and i/o is in progress on the fuse mount.
 

 


It seems to happen because of multi epoll thread between glusterd enable.

workaround is to make epoll thread to 1 and set ping-timeout to 0

    glusterd: disable ping timer b/w glusterd and make epoll thread count to 1
    
    Currently glusterd is crashing when enable/disable heal and i/o is in
    progress on the fuse mount.
    
    This is because of by default multi thread epoll in glusterd is 2.
    Workaround is to make epoll thread to 1 and set ping-timeout to 0
