Re: lots of InActConn

Hey, thanks for the aswers.

I could decrease the number of InActConn by decreasing the time of
tcpfin timeout from 10 minutes to 10 seconds.

That appears to not generated any problems.

Did someone know if this can cause any issue?


I'm using this lvs array for squid proxy.


Thanks and regards.
