[et-mgmt-tools] re: "invalid kernel" -- found the problem!

Some more details.

I hammered cobbler sync, initiated by webui and console and could not
reproduce.

But a simple service cobbler restart did the trick. Now I have dhcpd
listening on 25152 and a b0rk3d xmlrpc for cobbler.

In the cobbler.log I see (not surprising):

2008-02-05 00:26:30,696 - cobbler.cobblerd - DEBUG - started
2008-02-05 00:26:30,865 - cobbler.cobblerd - INFO - XMLRPC running on

service dhcpd restart cleans up that part:

[root at vinf02 ~]# service dhcpd restart
Shutting down dhcpd:                                       [  OK  ]
Starting dhcpd:                                            [  OK  ]
[root at vinf02 ~]# netstat -alp | grep 25
tcp        0      0 *:25151                     *:*
LISTEN      30016/python        
udp        0      0 *:25150                     *:*
30013/python   

But now still a missing 25152, so lets try with

[root at vinf02 ~]# service cobblerd stop
Stopping cobbler daemon:                                   [  OK  ]
[root at vinf02 ~]# service cobblerd start
Starting cobbler daemon:                                   [  OK  ]
[root at vinf02 ~]# netstat -alp | grep 25
tcp        0      0 localhost.localdomain:25152 *:*
LISTEN      30105/python        
tcp        0      0 *:25151                     *:*
LISTEN      30106/python        
udp        0      0 *:25150                     *:*
30103/python        
unix  2      [ ]         DGRAM                    3825
1144/rpc.statd      


All fine again.

Now for debugging that - not today, I am off to bed.
