I try to repeat to send the request many times at the same time, it will hang. Does anyone
have the same problem like me? It is OK when I run 2.0.35/worker MPM without SSL.

I have the same build over here, and ran this simple command on another machine:

curl https://apacheservermachine > bla

It ran without problems, but something funny happened. The load on the apache
machine sky-rocketed. Even *after* the request were done, httpd was still
using "all" my CPU, load jumped from 0.x to 6 and is still climbing. There is not a 
single connection to port 443 here (or 80, for that matter) now, but:

17245 www       18   0  5084 5084  3408 R     9,8  4,0   0:24 httpd
17248 www       19   0  5084 5084  3408 R     9,8  4,0   0:24 httpd
17244 www       17   0  5084 5084  3408 R     9,6  4,0   0:24 httpd
17249 www       18   0  5084 5084  3408 R     9,6  4,0   0:24 httpd
17252 www       18   0  5084 5084  3408 R     9,6  4,0   0:24 httpd
(...)
all 69 processes/threads/whatever

I'm running it with the default configuration as supplied with httpd-std.conf, but I
removed all index.html.* files and only left one index.html there to be fetched (the
index.html.en renamed to index.html actually).

*But*, using:
lynx -dump https://apacheservermachine > bla

doesn't trigger this behaviour, as well as running curl with http:// instead of
https://.
