Great input! Thanks. Solving the issue that way looks like a complete
rewrite of the source to me. What I have done in the code attached, is
that I have put the initial mmsx_connect call in a GstTask. This
prevents the mmssrc from locking up the event loop for a long time at
this point (which was my major issue for the moment).

However, there are two issues:

I do not read the data using a GstTask, so I suppose a server dropping
of the radar while listening to it would probably still lock the
application.

In the finalize method, I have a situation where I might have a live
GstTask (which is blocking on a socket). Trying to do a gst_task_join
will freeze the application here, so that is not an option. For the
moment, I simply do nothing - which I suspect is a leak.

Best regards,
