Question

We are accessing the Citrix using the Linux command line (storebrowse/adapter  commands). On occasion (usually everything works well) the executable works fora very short period and then exits with a status of 0.

Looking at the log files we see the following for a failure login:

2022-02-23 11:50:10.193 [WD] <P13420> citrix-wfica: Can't create serial number file '/etc/icalicense/clientlicense' - 'File exists'

For a successful login we see the following:

There doesn't seem to be any network issue at the same time of the problem, and it seems to occur sporadically.  The server is a simple setup, no fail-overs or something like that.

 

Does anyone have an idea as to how to debug this further?

Hallo Yaacov Fenster,

6 months later we have the same problem. With one difference, it occurs regularly. Have you solved the problem in the meantime? And if yes - then how?
