Hi,I have VPS Parallels Plesk Panel version 10.4.4 (centos-5-x86_64) and I would like to change the value of tcp_keepalive_time.I tried to edit the sysctl.conf file using root:
I'm facing a lot of TCP timed-out on a busy cache server and here below my sysctl.conf configuration as well as an output of netstat -st
Kernel 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3 x86_64 GNU/Linux
Any advice or help would be highly appreciated
# cat /etc/sysctl.conf
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
fs.file-max = 65536
net.ipv4.tcp_low_latency = 1
I'm running comet server on linux (Debian).
All the connections are proxied by nginx.
And my time_wait/live rate is too big although I set reuse_connections.
