Because of media-relay running in openvz virtual container it inherit
kernel modules like ip_table, ip_conntrack, nfnetlink from host node, so
yesm ip_tables module like others loade before media-relay start.
Below is a list of running modules.

Unfortunately it is very hard to migrate to python > 2.4, because CentOS < 6.0
don't support other versions and hard depend on python 2.4.

Now I'm trying install Scientific Linux 6.0 in openvz virtual environment
to test python 2.6.

I have a question regarding which python version are recommended to run
media-proxy (python 2.6, 2.7, 3.2) ?

Yes, ip_tables loaded: ip_tables 57440 3

Was it loaded before or after starting the media-relay?

Is it possible that error because of python 2.4?
Not precisely that, but you'll get a bunch of other errors because of
this. Unfortunately I can't test/reproduce this. Anyway, you better
upgrade to Python 2.6. Regards,
