Noticed virtual services stopped responding intermittently and it works fine after restarting the VSE, so trying to identify the root cause for the failures.

Environment

All supported DevTest releases.

Cause

Cache data in lisatmp_x.x.x folder causing these errors.

x.x.x = DevTest release number

Resolution

Instead of just restarting the VSE, doing the below steps will resolve this issue:

1. Stop all the DevTest services running on the VSE machine.

2. Delete the entire DEVTEST_HOME\lisatmp_x.x.x folder.

3. Start all of the DevTest services running on the VSE machine.
