Description of problem: glusterfsd is reaching 1200% CPU utilization Version-Release number of selected component (if applicable): glusterfs-3.8.4-18.6.el7rhgs.x86_64 (Upgraded Node) glusterfs-3.8.4-18.4.el7rhgs.x86_64 (Non-upgraded node) How reproducible: Customer Environment Steps to Reproduce: Gluster cluster is replica 3 with 2 data nodes + arbiter node. Customer has upgraded arbiter node to RHEL7.4 with 'yum update' command. They have rebooted the node and everything was working fine. They repeated the same with another data node but when node comes up after upgrade, CPU utilization got spiked and volume become in-accessible (Work load is a RHEV environment where VMs are consuming this volume becomes non-responding.). Actual results: glusterfsd is reaching 1200% CPU utilization Expected results: Glusterfsd processes shouldn't got spiked to the amount where volume become in-accessible Additional info: Gluster volume is being used in RHEV environment as a back-end storage for VMs.
