Yes, I can confirm this. It also happened to my machine.
Here is what I did.
. insmod ip_vs_pcc.o
. ipvsadm -A -t 192.168.10.100:80 -s pcc
. ipvsadm -a -t 192.168.10.100:80 -R 192.168.11.10
. ipvsadm -L
it listed correctly.
. ipvsadm -d -t 192.168.10.100:80
### this cause the system locked up.
I have not spent time investigate this yet. For now I just try to avoid
deleting.
Regards!

Subject: Bug in LVS-0.6
I think I found a bug in LVS-0.6 for 2.2.10. It looks like when someone
deletes a real server from the hash, the actual entry that says "hey, I'm an
existing real server" isn't deleted. (I haven't had time to look at the
code, but I'm guessing this is the case)
Try this: (SYNC first! And be sure you don't have processes in the
background. This may cause you to need to reset your computer.) (Feel free
to change the IP addresses)
sync
ipvsadm -C
ipvsadm -A -t 10.200.0.15:80 -s rr
ipvsadm -a -t 10.200.0.15:80 -r 216.69.192.196 -g
ipvsadm -d -t 10.200.0.15:80 -r 216.69.192.196
ipvsadm -d -t 10.200.0.15:80 -r 216.69.192.196
At that point, if things work correctly, I should get this:
setosckopt failed: No such file or directory
No such destination
Which is fine. That's what I get if I delete any real server that never
existed in the first place. However, what I *ACTUALLY* get is this:
IP_VS: ip_vs_del_dest(): destination not found!
setosckopt failed: No such file or directory
No such destination
And then the machine locks up. It looks like init still is functioning, as a
CNTRL+ALT+DELETE does kick it into runlevel 6, however... it doesn't get
very far into runlevel 6 until it completely locks up.
Let me know if anyone else can confirm these results.
Try:
adding a virtual server
adding a real node
deleting that real node
deleting it again
If there isn't a bug, then it'll just act as if you tried to delete a server
that never existed... but if there is a bug... then your machine will
lockup.
All the best --
