VDA agent fails to start; citrix-dotnet: Failed to connect with logd messages

[Ercan Yilmaz]

Lately I see often that the vda agent fails to start and see the following error during startup of the Linux vda agent:

Anyone any idea what the root cause is for this issue. Restarting services does not help.

The current solution is a complete removal and reinstall of the vda agent and all dependencies (yum remove postgres*; rm -rf /var/lib/pgsql), which is not desirable.
