Hi Guys,

As I'm not very well known with TCP/IP = I need to=20 ask you this question :) Hope it isn't too stupid ;)

When I do a netsat -s I get a line = which says=20 listen que overflows:

4104=20 listen queue overflows

How bad is this?

I already tried to solve it by doing=20 this:

sysctl -w = net.inet.tcp.recvspace=3D32768
sysctl -w=20 net.inet.tcp.sendspace=3D32768

And although the amount decreased = considerably, the=20 problem is not completely lost. I am wondering if it is wise to enter = bigger=20 values?

Some background info: this server is = used to host=20 some sites and some other stuff and is currently doing an average of = 5mbit/s=20 traffic. Peak traffic is about 8mbit. Network cards in the machine are = both=20 Intel EtherExpress (which is currently used) and the 3Com 3c905C (which = we don't=20 use anymore, because there are big problems with this card.). A total of = 1500MB=20 of Ram is installed, and the machine is a Dual 866MHZ system (intel p3). = Motherboard is an Abit, so VIA chipset.

All information is greatly=20 appreciated,

Thanks,

Ali
