(also observed under FreeBSD 2.2.7-STABLE)
>Description:
We have only observed this recently on two or three of our 150+ Web servers.
What is happening is that on an otherwise normal and relatively quiet server,
the httpd processes will stick around in the "R" state, with no activity,
until eventually all slots are full.  The most obvious datum is that on the
mod_status report, the field Acc is always of the form X/Y/Y, where the last
two numbers are the same.  This is *not* true on any of our servers except
for a couple.

We have checked for SYN floods, unusual network activity, tried disabling
busier sites on the server one at a time, cleaned up all .htaccess files,
etc.  We are not using serialized accept.  We have tried with and without
KeepAlive, at different levels.  Our Timeout is set to 2400.  I have verified
that the configuration is identical to all other servers, except for the
virtual hosts listed.

ktrace on the parent shows only a series of sleeps and signals.  ktrace on 
any child shows no system calls whatsoever.

Attached below is the leftmost columns of our mod_status output after the
server runs for a few minutes.

>How-To-Repeat:
Unknown.  We once "fixed" a server when we found a .htaccess file that had no
carriage return in it - but this does not appear to be the case in the most
recent incidents.
I believe this is the same problem described in the PR #1724, which was never
completely understood and resolved.
>Fix:
Something is causing httpd processes not to return to the idle state.
We are working on an upgrade to Apache 1.3.3 to see if this resolves the
problem.
