I've searched bugzilla but didn't see anything like this. I've got RH's
apache 2.0 server running, pushing static HTML pages and one perl CGI
program. What happens is that httpd processes apparently get hung in the
"Sending Reply" phase. This causes the master httpd process to keep
spawning sub-processes until it hits 152 processes (two more than the
config file MaxClient limit of 150). It then stops serving any data at
all.
/etc/init.d/httpd fullstatus before reaching the 150 limit gives the
following scoreboard:
Apache Server Status for localhost
Server Version: Apache/2.0.40 (Red Hat Linux)
Server Built: Apr 7 2003 09:19:34

Scoreboard Key:
"_" Waiting for Connection, "S" Starting up, "R" Reading Request,
"W" Sending Reply, "K" Keepalive (read), "D" DNS Lookup,
"C" Closing connection, "L" Logging, "G" Gracefully finishing,
"I" Idle cleanup of worker, "." Open slot with no current process
After that it lists all the busy processes and what they are sending. In
my case, it's all different types of files including jpgs and html
files. It's not any one file, it's not the single CGI program, it's
basically everything.
This site worked fine with Apache 1.3.X. I tried switching to the
'worker' version and although that version doesn't spawn a bunch of
processes, it still reports stuck processes like the normal version.
Any ideas before I open a bug on this?
Thanks,
tjb
