Hi.
I experienced a situation where Libreswan (libreswan-3.15-5.3.el6.x86_64) and with libreswan-3.17-1.el6.x86_64 which  went into a "stuck" or failed? state on 2.6.32-573.18.1.el6.x86_64 RHEL6

I could not stop it using 
time sudo /etc/init.d/ipsec stop
Shutting down pluto IKE daemon
^C
real    5m52.619s
user    0m0.014s
sys     0m0.014s
 (stuck for more than 5 minutes)

And I could not get result for /etc/init.d/ipsec status because the command also got stuck.
Could I issue a kill command with any option to capture some debug information?

Thanks.
Mike
