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.

What kind of behaviour are you observing?
