Do you by any chance use persistent database connections from php. In that
case you might want to look at setting a limit on those connections, or
maybe disallow (or remove the use) them. Also fiddling with the apache
client settings might work. 200 clients is a lot, so probably some are out
on their backs (dead). In the config you can control restarting of those
clients (how long they are allowed to be alive). If you have a really busy
site, they might actually all be in use in which case increasing this
limit is the solution.

Good luck,
Paul
