Hi,
I have put an apache server in front of my primary webserver as a proxy
in preparing to move to a new webserver. In testing it worked fine, but
under load (we have snow today and everyone it hitting the website to
see if school is open), I am getting all kinds of timeout errors and
service not available pages. In server-status on the proxy, it does not
look like it is loaded:
Server load: 0.40 0.27 0.23
Total accesses: 99516 - Total Traffic: 2.6 GB
CPU Usage: u4.35 s3.08 cu0 cs0 - .382% CPU load
51.1 requests/sec - 1.4 MB/second - 27.4 kB/request
91 requests currently being processed, 59 idle workers

Errors are:

connect to 10.1.3.100:80 (webold.nsd.org) failed

Any help/ideas are appreciated.
