Server hangs when deleting checkpoints

Anonymous

We have Windows failover cluster setup with 3 Windows 2019 hosts running Hyper-V. They all connect to shared storage on HP MSA 2062 iSCSI SAN using 10GB ports.

When deleting checkpoints on one VM causes other VMs on any of the hosts to be non responsive (extremely slow) . It also reports event ID 129 on the VM. As a result taking backups results in outages for end users.

When this happens host desktops are accessible and does not show any performance issues. There is nothing significant indicated on the performance counters as well.

Any help to resolve this issue is greatly appreciated.

Thank you
