Yes,
I am using libnetfilter_conntrack for adding expected connection
through Application Proxies. Now, sometimes my proxy hangs and when I do gdb
on the core generated, recvmsg call is in waiting mode.
I have changed libnetfilter_conntrack slightly to make it single
socket for my Proxy. I do nfct_open at time of proxy start, do
nfct_create_expectation every time request comes and nfct_close when proxy
ends.
Rgds,
Nishit Shah.

What kind of behaviour are you observing? Please elaborate.
