Help! kernel: TCP: drop open request from xxx.xxx.xxx.xxx
I am running Red Hat 8.0 with the apache web server and all of the sudden
I am getting the following errors, tons of them every second and the
web server has slowed to a crawl and not responding to requests. I
restarted the system and no help. Does anyone know what may be going
on and how to fix the problem? The server is a Dual 1GHZ Intel system and
gets a good deal of traffic, the kernel is 2.4.18-14smp
from /var/log/messages

All of the sudden the errors stopped, but the traffic remains fairly high.
