Re: [squid-users] Squid3 and lots of FIN_WAIT1

I think i've got something.
My LVS seems to have very very low timeout.
So, LVS timeout TCP session too soon and client FIN & ACK can't reach
the correct squid box, which can't close TCP session properly.
This morning i've raised LVS timeout, and for now, FIN_WAIT1 have gone away.
I hope this will be durable. Now, i need to monitor other time to
confirm this.

Thank you.
David.
