Until you identify what specifically spiked then you don’t know what to prevent.

Do you have a TAC case open yet?

Thanks Ryan. Nothing really standing out on the ESXi side.

Any suggestions to prevent this in future?

The VMware KB articles suggest a higher timeout on application side so 
transient issues and conditions on the VM side of things don't negatively 
impact the application.

That's your culprit right there. That 16 second sdlrouter thread timer is one 
of the few things I bet hadn't changed since 4.x.

Can you look at esxi stats for that time period to see what the host thought 
was going on?
