[squid-users] Busy Transparent Cache Causing Problems

[Jay W. Reffner]

I've got an OpenBSD box running Squid 2.5 Stable 5 that's pretty busy. When it gets to around 30% squid process usage, my Layer 4 transparent switch thinks that squid's down and kills my L4 redirection even though it's not really. So what happens is when my L4 switch backs off and stops forwarding HTTP requests to my squid box, it relieves the load enough to the point where the L4 switch then thinks it's back up and starts forwarding HTTP requests again.

My question is, is there something I can do (short of buying a new box) to help this, like tune the kernel for better performance or something to keep my L4 switch from giving a false outage of squid? FYI, my L4 switch is a Nortel Alteon 184.

TIA,
Jay
