[OpenSIPS-Users] media-relay error - operation not permitted

[John Quick]

Hello all,

I am investigating exactly the same error that Jeff has just reported.
Feb  8 16:10:05 media-relay[16199]: Traceback (most recent call last):

This is happening on a server that is not yet taking any live traffic. What
I see is that Mediaproxy behaves fine when it has just been restarted, but
after it has been running for a few days (with little or no activity), I
start to see these errors in /var/log/messages when I make a call.

I have not seen it on earlier installs, but I have changed several things
between the good install and the one that fails. For example, the newest one
is on CentOS 6 and the reliable ones are on CentOS 5.

Here is a list of the dependency packages, with versions, used on my newest
servers:
Iptables      1.4.7
libnfnetlink        1.00
libnetfilter_conntrack     0.0.100
libgcrypt      1.4.5
gnutls       2.8.5
python     2.6.6
python-zope-interface    3.5.2
Twisted	12.2.0
python-gnutls	1.2.4
python-application	1.3.0
python-cjson	1.0.5
