Hi,I run a Squid Web Cache system on a RH 6.2 system with  a 2.2.16-3
kernel. I also use ipchains to redirect connections to port 80 to the
web cache port.

Using netstat -s I can see a large number of packets in the

"packetd dropped from out-of-order queue because of socket buffer
overrun"   category.

I've tried increasing the tcp  buffer sizes by using the following

echo 70500 > /proc/sys/net/core/rmem_default
echo 70500 > /proc/sys/net/core/wmem_default
echo 70500 > /proc/sys/net/core/rmem_max
echo 70500 > /proc/sys/net/core/wmem_max

but it doesn't seem to make any difference

So ...

1). how can I actually find out what the tcp socket buffer sizes are (
solaris netstat command shows the butter sizes in operation for a
particular connection)
2). given that I'm still seeing the errors, how can I resolve the
problem

Any help appreciated
alex
