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


Ercan Yilmaz

Question

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

 

# systemctl status ctxhdx ctxvda ctxjproxy

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.

 

Running:

OS: CentOS Linux release 7.9.2009 (Core)

kernel: 3.10.0-1160.36.2.el7.x86_64

vda agent: XenDesktopVDA-21.04.0.8-1.el7_x.x86_64

dotnet:

rh-dotnet31-runtime-3.1-3.el7.x86_64
rh-dotnet31-libcurl-7.61.1-11.el7.x86_64
rh-dotnet31-dotnet-host-3.1.16-1.el7.x86_64
