Subject: [lvs-users] Load-balancing: FTP data traffic results in Kernel oops in 2.6.36.2 , x86_64

hello,

I was testing IPVS to load-balance FTP servers in linux 2.6.36.2 x86_64 system.

My configuration is below:


-A -t 10.11.20.132:21 -s wrr
-a -t 10.11.20.132:21 -r 192.168.132.231:21 -m -w 100
-a -t 10.11.20.132:21 -r 192.168.132.232:21 -m -w 100

This is resulting in system oops whenever FTP client fetches data ,
say using , "ls" or "mput". I tested both active and passive mode,
oops happens in both scenario.

I did see kernel mainline for any fix, but there are no fix which has
gone in after 2.6.36.2 for this issue.


This is what I managed to write down. The first part scrolled off
screen with no scrollback - and no logfiles.

ip_forward
ip_recv_finsih
ip_recv
__netif_recieve_skb
e1000_clean_rx_irq
? enqueue_task
net_rx_action
__do_softirq
call_softirq
irq_exit
do_IRQ
ret_from_intr
native_safe_halt
default_idle
c1e_idle
cpu_dile
rest_init
start_kernel
x86_64_start_resevation
x86_64_start_kernel

Apologies if this is already fixed in mainline, please point me towards the fix.

Thanks,
KB
