Citrix Desktop Server with PVS on VMWare crash


Enrico Rudolph

Question

Hello,

 

my customer work with:

 

PVS 1906.1

Virtual Apps and Desktops 1906.2

VMWare 6.7 Update 2
Windows Server 2016 (fresh patched)

On the VMWare cluster run many Systems, only the Citrix Desktop Server Crash. If the crash happen, i can not ping the system and the console in VMWare is only a black screen. The only way to get access to the System again ist to reboot the guest system.  

In the logs of the PVS Server i see no error.

CIS say the PVS Server are fine.

In the logs (on permanent disk) of the Desktop Server i see no error.

A Windows debugfile (on permanent disk) is not written.  

On the VMWare log i see only this:

The vDisk is ok, cache is on 4GB Ram with Disk overflow. The cache disk is not full. 
 

Know any body this problem?

 

I need a idea how i can find the problem. A possibility to log the crash or anything else to debug the problem. 

Regards
Enrico Rudolph
