I have noticed a memory and thread leak in the Windows Virtual Disk service
- or vds.exe from the process list. This service is set to Manual by default and gets started when starting the XymonPSClient service on Windows 2008 R2. It starts off using 32 threads, but grows forever, the virtual memory and physical memory (which starts under 6 MB) used slowly grow too.
Has anyone noticed this problem and do they have a solution to it?
On Windows Server 2012, the Virtual Disk service does not get started by Xymon Windows Powershell client, so it's obviously not started directly by the client, but by a request for information. I looked into known memory leaks for vds.exe and the one I found was not applicable to 2008 R2, only 2008 and Vista. The version of vds.exe we have is later than the version with the fix: 6.1.7601.17514 from 2010.
The quick workaround is simply to stop the Virtual Disk Service - but as soon as the PSclient has used it, it does not stop properly and terminates unexpectedly, so one needs to set it not to restart on crash, or stop it immediately after starting, or to Disabled. But it would be good to know why it is starting, not stopping, and leaking threads / memory!
Kind regards,
