Re: [squid-users] code red is making horrible on our network

I'll try that on Monday. For the weekend we left transparent proxy turned off for safety.

It looks like it's going to do something good because yesterday I saw the same thing as you did. I had about 130 of these sockets, which matches what you've said the limit is: 128.

I guess everyone with this problem should give it a try.

  Hi All !
  I think I find  the solution & the problem
  echo 2048 >>/proc/sys/net/ipv4/tcp_max_syn_backlog 
  because its only 128 by default
  sockets are flooded
  and look at this :
  netstat -na | grep SYN
