 New Comment:

Thom and I already spoke about this bug, and I'm going to
try to reproduce it locally as soon as possible, but
at this point I'm not sure if it's Apache's fault or
something in the apache2filter. I'm leaning toward
a problem in the latter. I'm also going to try to reproduce
this under the prefork MPM, but if someone beats me to
it, please submit your results here.

(Occurs with both HEAD and 4.2.1). Only tested with worker mpm. (This
only occurs when the php module is loaded)
to reproduce:

attempt to restart (gracefully or otherwise) a running apache2 server.
Make a page request while apache is still starting the child
processes.
