fd leak in apache? on one of our reverse proxies we have MaxKeepAliveRequests and MaxRequestsPerChild set so as to make it difficult to leak. This made our proxy go from running out of 4000 fds in a day to averaging about 120 fds in use.
From what I've seen it's usually MaxRequestsPerChild that has the biggest effect on leaks, both mem and fd. Your mileage may vary. I wouldn't bother too much about MaxKeepAliveRequests unless you're having a problem in that area.
