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.
System setup info is:
