Description David Naori 2011-05-23 08:41:33 UTC 
Description of problem:
Sometimes when stopping vdsmd- not all processes are being killed and still bounded to 54321 socket.

[root@camel-vdsb storage]# /etc/init.d/vdsmd stop
Shutting down vdsm daemon: 
vdsm watchdog stop                                         [  OK  ]
vdsm stop                                                  [  OK  ]


[root@camel-vdsb storage]# ps aux | grep vdsm
vdsm      4535  0.0  0.0 1451148 26212 ?       S<   11:18   0:00 /usr/bin/python /usr/share/vdsm//vdsm
vdsm      4538  0.0  0.0 1526928 28264 ?       S<   11:18   0:00 /usr/bin/python /usr/share/vdsm//vdsm


[root@camel-vdsb storage]# lsof -i -Pn |grep 54321
vdsm       4535    vdsm    7u  IPv4 1843887      0t0  TCP 10.35.116.2:54321 (LISTEN)
vdsm       4535    vdsm   24u  IPv4 1845174      0t0  TCP 10.35.116.2:54321->10.35.77.4:51782 (CLOSE_WAIT)
vdsm       4538    vdsm    7u  IPv4 1843887      0t0  TCP 10.35.116.2:54321 (LISTEN)
vdsm       4538    vdsm   24u  IPv4 1845174      0t0  TCP 10.35.116.2:54321->10.35.77.4:51782 (CLOSE_WAIT)
