I'm using STAX 3.4.0. If it really should not happen then it is likely a problem on my end, not STAX's end.. :)

Paul,
What version of STAX are you using?
This should not happen if you are using a current version of STAX because
each STAX job creates its own Python Interpreters, each with a new
PySystemState. We have many STAX users who have STAX service machines that
run 10+ large jobs simultaneously and haven't had any issues reported like
this. If this really is happening, then it's a bug.

[staf-users] Python variable
scope ... between jobs?
Hello,
I sometimes have strange python (/jython... I will probably refer to it as
python though...) variable issues - e.g., it values from one variable end
up in another variable for whatever reason, or a class somehow gets messed
up and Python complains that an instance of class X does not have attribute
Y when I know for a fact that it does :)
This happens *much* more frequently when many jobs are running (10 or
more... large jobs; if they all completed, they would generate over 100,000
user logs, not sure how many non-user logs, use around 20 XML files that
can have up to 4000 lines in them, etc).
I'm working through possible variable scope issues... question is: is there
a possibility that the python variables/scope/maybe shared memory is
getting mixed up or leaked amongst the many running jobs?
Not necessarily saying this is happening but asking if it is possible while
I explore various reasons it may be happening... :)
It also seems to happen more frequently when multiple jobs are running
through the same XML sections (and thus the same python/jython scripting)
at the same time...
Thanks!
Paul
