Hello,
I use 2 directors with heartbeat in LVS-DR front of 2 real servers (squid).
I use the Debian Sarge default kernel 2.6.8 :
lvs1:~# uname -a
Linux velvet 2.6.8-2-686-smp #1 SMP Thu May 19 17:27:55 JST 2005 i686 GNU/Linux
and ultramonkey3 with ipvsadm 1.24+1.21-1.
This cluster works well for 1 month, but I've seen I've dead connections on
the director with lvs-rrd :

specially in the month view we can see I've 60 000 active connections but in
reality I've just 5300 active connections :

____________________________________________________
The director show 19988+19991=21979 active connections.
lvs1:~# ipvsadm
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP vip_squid:www wlc
-> realsquid17:www Route 100 19988 31468
-> realsquid16:www Route 100 19991 31739
____________________________________________________
But in the first real server I've just 2621 active connections.
realsquid17:~# cat /proc/net/sockstat
sockets: used 2623
TCP: inuse 2621 orphan 97 tw 1932 alloc 2623 mem 668
____________________________________________________
and in the second real server I've just 2653 active connections.
realsquid16:~# cat /proc/net/sockstat
sockets: used 2581
TCP: inuse 2563 orphan 74 tw 2060 alloc 2563 mem 1036
____________________________________________________
I can reboot the director, but I think it's not the solution
Have you got an idea of the problem ?
Regards,
Marc
