Hi centos users,
I've installed a load balancer using lvs (with direct routing).
I use
LVS with a heartbeat configuration and ldirectord and I don't use persistent connections.My problem is when i am running "ipvsadm -lcn", I can see a lot of connections with the CLOSE (or others states) state going from 00:59 to 00:01, and then going back to 00:59.
In other
words these connections should be dropped after they timed out
but the
counter is reseted to 60. I wanted to compare these entries on my real
servers with
netstat and I can say that these connections are not on my real servers and they should be dropped from ip_vs_conn entries. My connection table is growing and I'm wondering if this connections table will not be too huge after a
long
time.
I'm afraid not, all our systems are setup using masquerading NAT. That was going to be my next question if it turned out (as it did) that you're using kosher RPMs. :)
I've only ever had LVSes configured with NAT so have no experience and only a vague memory of how DR works from the docs. If no one here can point you in the right direction there's a dedicated LVS list too which might be worth searching the archives of and then questioning if you can't find an answer.
And, to follow up my own post, I've just had a quick look through my LVS list mails and spotted:

There's no follow up from the OP which may or may not be a good thing. :)
It appears a kernel upgrade to 2.6.18 (!) may help. You might want to fire off a mail to the OP and ask if he had any success. I have the un-obfuscated address in my mailstore, I'll send it offlist.

Thanks for your help, but I will wait for an official patch from centos, I hope that I will be heard.
