Since updating our App Volumes Manager and Agent from v2.12.1 to v2.13.1 we are seeing around 1 in 3 logons to our non persistent linked clone pools fail with the error The connection to the remote computer has ended. We seem to see this error quite quickly, only a few seconds after clicking on the pool in the Client. Removing the v2.13.1 agent and going back to using v2.12.1 immediately resolves the issue.

I've read the article here https://kb.vmware.com/s/article/2151948 that seems to suggest this error can occur in large scale deployments of AppVols but our current use is very small (10 users or so). This article also says the symptoms occur after being logged into a VM for a few minutes then being kicked off which doesn't match our scenario either. They also suggest using a writable volume script as a fix but we don't use writable volumes..

I've trawled the Clients logs for further clues but there's very little to indicate the root cause. Everything seems to be going well in the logs until it displays the error message with no underlying reason given.

Has anyone else had any experience of connection errors since upgrading their AppVols?
