DOS RAM usage on ESXi 6.7

[WPaulini]

Hi I run a DOS 6.22 on a ESXi 5.5 without any problems. Now I istalled a new ESXi 6.7. For upgradign the system i moved the DOS VM with vShpere to a different ESXi and than back again. Since the upgrade my DOS has problems on the ESXi 6.7. After a few days the needed RAM is rising from 10 MB to several 100 MB and the DOS is nor reacting any more. After a reboot of the VM everything is OK and running for some days. The other VMs on the Server (all Windows and Linux) dont have this problem. It is only the DOS. Anyone an idea?

Do not assign more RAM for  a DOS VM than DOS can handle - if it rises to several 100 MB you may have assigned too much.
