[lvs-users] connection broken during two hours by using LVS as load balancer

[richard zhao <rich4tech@xxxxxxxxx>]

Hello, All
I developed a Client/Server program in which client will establish a persistent 
connection with Server and then client and server will maintain this connection 
for a very long time. this week, I use LVS as load balancer. I found that the 
connection between Client and Server are broken at the exact two hours. if I 
don't use the LVS, the connection never break under the same environment. For 
this LVS,  the packet forwarding method is gatewaying, the scheduler which I 
tried is lblc, I also tried --persistent. they have same results.  Does anyone 
have such experience? could anyone explain why that happened and tell me how to 
avoid. thank you very much in advance.
