Cause

This issue occurs when a specific routine task (vScheduleCheckVsanConfigLro) is started when the vCenter's LRO job queue is already full of queued tasks. It causes vpxd services on the vCenter to stop responding. This can further lead to do-host not obtaining information from the configured node.

Review the VMware article vCenter Server vpxd service crashes due to "Too many outstanding operations" (89742) for more information This hyperlink is taking you to a website outside of Dell Technologies..

Resolution

This issue is addressed in vCenter Server 7.0 Update 3i (build number 20845200).

Workaround:
Change the particular parameters config.vmacore.threadPool.TaskMax in vCenter to a value above or similar to 200.

Restart all the services on vCenter and the vpxa and hostd services on each host. Place each host in maintenance mode before running the commands on it. 
On ESXi hosts:
#Rolling restart the ESXi host daemon and vCenter Agent services using these commands:
/etc/init.d/hostd restart
/etc/init.d/vpxa restart

On vCenter
#take a snapshot of vcenter server
#service-control --stop --all
#service-control --start --all
