I am seeing similar or probably related issues in AKS.

I can reproduce by issuing iisreset /stop after sigterm is sent to the container, the entry point hangs indefinitely.

Also, I am seeing too often pods stuck in destroying status requiring decommissioning and spinning a new node replacement. Some of these are IIS other are MSQL.

I also noticed that overloaded nodes have terrible issues terminating pods, it's easy to reproduce by using very small nodes (i.e. the cheapest B series VM) and putting some decent load into the the node becomes unresponsive and hangs (no RDP to the node is possible).

I will be capturing kubelet logs when any of this happens again.

We've stopped working on this issue because we are having a bigger problem with w3wp.exe having locked pages when the w3wp.exe terminates causing the node to blue screen

Hopefully you can have a solution for me after we get our blue screening problem fixes

Have you escalated this to azure support? BSOD on an AKS node looks like something they should be looking into.

Hey @deedubb, can you provide some repro steps where you can trigger this issue?

We upgraded to 1.28, we've been busy dealing with all the instability after the upgrade - hns unable to deallocate for containers, IP address allocator going offline and refusing connections, crashing nodes due to protected memory still being referenced... I'm sure I'm missing a few.

I have a laundry list of feedback for running windows nodes in AKS -- tldr: don't -- however I do not have repo steps
