Yes, the session is enabled (see below why)- sorry for not mentioning this.

Since this script will be used in a production environment with the session
enabled due to the nature of the application, and the error also occurs when
the session is enabled, I thought that I didn't need to disable it. The
session should actually prevent such an issue from happening alogether,
since it serializes access to a script.

Yes, I created a diagnostic file where the script writes trace statements in
various points, and also monitored the process exec-ed by the script, which
is no longer in the list of active processes by the time the script hangs.
