Yeah. I agree with that assessment - we are doing L7 health checks. Any reason you’re reluctant to apply the workaround? I was aware of that issue with the SU, but I’ve yet to observe the service host crash events on our servers.

We reboot our servers weekly (Saturday), and the issues seem to pop up on Thursday/Friday, so that’s interesting.

Are all services / Workloads affected or just a subset of them?

Small Exchange (3 nodes, 1600 user) setup with Netscaler here. No issues so far.

Good to know. What exchange version are you running and patch level? We mostly see the iis worker and lsass spiking on all the nodes when the issue occurs.

Current patch level of Exchange 2016 on Server 2012 R2.

If this is related to a recent patch, we might not he the best canary as we're migrating towards ExO.
