I was thinking about which requests those processes are handling right
now. AFIK Apache logs when a request has been served, so if something
goes wrong before that, it will not show up in the log files.

If the server-status page is available, could you fetch it, and see if
anything unusual is going on? The scoreboard (which is displayed by the
server-status page) is the place to get information about what Apache is
doing, while it is doing it.

Have you considered lowering the MaxClients setting?
