Summary: Crash on force_tcp_conn_lifetime

Initial Comment:
After the patch proposed on issue #3546167 we are experiencing crashes with the following backtrace:

Program terminated with signal 11, Segmentation fault.
#0  force_tcp_conn_lifetime (rcv=0x8d1a814, timeout=3610) at tcp_main.c:1180
1180	tcp_main.c: No such file or directory.

Apparently the connection is not found in the connections hash. Unfortunately I'm not all that familiar with that part of the code to provide a patch. What I did notice though is that all functions which operate on the connections hash hold a lock and this one doesn't. Could that explain this?

Thanks,
