I don't know if I can help or not, but I'll try. I am currently running 
apache 1.0.5, and have just downloaded version 1.1.1 from the source -- 
http://www.apache.org -- it's only been up as a release for about a week.

Anyway, check the error log entries on timeouts against the corresponding 
entries in the main access log. I can think of a few reasons for send 
timeouts, depending on how busy your site is and what capacity you have. 
Such as:

	Too many accesses in a short period of time, especially with 
limited bandwidth, might cause some packets to get lost and never be 
acknowledged. If you have the bandwidth and capacity, maybe increasing the 
max number of child server processes could help.

	If the client disconnected without getting a "stop" request to 
your server, you should see a timeout.

Before I speculate further, I'd need to know a bit more. How often do 
these timeouts occur? At any particular time of day? What's your average 
load, and what's your load when the timeout occurs?

Match up the timestamps in your error log and your access log. Do the 
timeouts occur from a single domain? Maybe a single user?

In any case, the more information you can get from your log files, the 
easier it will be to narrow down the source of your problem.

Regards!
