[Thinlinc-technical] tlclient on Debian Buster

I believe we have found the cause of the problem. If any local
application is listening on a socket with an adress consisting of only
'\0' tlclient will hang when trying to connect. We are able to
consistently reproduce this behavior even on non Debian Buster systems.
However, the other customer we had that reported the same problem, also
using Debian Buster, said irqbalance was listening on a unix socket
with that address.

You should be able to find the application that is causing this error
on your system by running this command on your client machine:

 ss --unix -l -p | grep "@ "

That command should show you the pid of the process listening to that
problematic socket address. Could you check which process that is?

Best regards,
