I am using Xubuntu 12.04 with kvpnc 0.9.6a-2 - same problem here with
racoon+ipsec how cwsupport described it.
Hitting diconnect leads Kvpnc to hang. An strace shows that the application
tries to kill the tail-process:
<snip>
kill(2689, SIGKILL) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {0x7f813c0e7730, [], SA_RESTORER|SA_NOCLDSTOP,
0x7f813bd85cb0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0}, ^C <unfinished ...>
</snap>
This messages apears over and over again. So I searched for the process with
the ID 2689:
2689 ? Z 0:00 [tail] <defunct>
So, its a zombie, this process could not be killed. The father of this
process is raccon which isn't stopped at this moment. If I kill racoon
manualy nothing changes. The father of racoon is kvpnc. But this hangs
....
