[Gluster-users] heal hanging

[David Robinson]

>I am having issues with 3.6.6 where the load will spike up to 800% for 
>one of the glusterfsd processes and the users can no longer access the 
>system.  If I reboot the node, the heal will finish normally after a 
>few minutes and the system will be responsive, but a few hours later 
>the issue will start again.  It look like it is hanging in a heal and 
>spinning up the load on one of the bricks.  The heal gets stuck and 
>says it is crawling and never returns.  After a few minutes of the heal 
>saying it is crawling, the load spikes up and the mounts become 
>unresponsive.
>
>Any suggestions on how to fix this?  It has us stopped cold as the user 
>can no longer access the systems when the load spikes... Logs attached.
