Would
restarting any of the servers periodically help?
Suppose it takes X minutes to restart a server, and
that the "lag" problem puts Wikipedia out of operation
for Y minutes -- where X << Y. Maybe then this would
be a good "band-aid" for the problem.
It takes all of a couple seconds to restart apache; I've set it to do a
"graceful" restart every half hour during US daytime, which more or less
coincides with our peak hours.

Does restarting apache also untangle the gridlock of database queries?
