--- Comment #10 from Jean-Loup C. <p...@hfox.org> ---
I have a similar behavior as described here (with no ssl involved) with httpd
2.4.9.

I got a lot of AH00485: "scoreboard is full, not at MaxRequestWorkers", httpd
is still serving requests, however one worker is in graceful finishing state
and is taking 100% CPU.

The worker was in this stat for about 24h, until I kill(1)ed it.

Threads stats:

__________________W_____________________________________________
GGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG

Unfortunately I don't have any other info from the status page.

strace of the worker shows an epoll_wait infinite loop:

    [...]
    epoll_wait(10, {}, 128, 100)            = 0
    epoll_wait(10, {}, 128, 100)            = 0
    epoll_wait(10, {}, 128, 100)            = 0
    [...]

mpm event config:

    StartServers         1
    ServerLimit          4
    MinSpareThreads      4
    MaxRequestWorkers    128
    ThreadsPerChild      64
    ThreadLimit          64
    AsyncRequestWorkerFactor 4
