Out of memory crash during hdd speedtest in vm

Can confirm @hhoehle's observation.

Proxmox 7.1.10 (yes i know, thats not the most recent one, but this is just a test system)
Windows Server 2022 VM with VirtIO-Block Disk crashes under CrystalDiskMark. (OOM in syslog)
Changed cache from default to write back and no more crashes.

VM disk and Proxmox are on two different zfs pools
