ulimit -n 100
apachectl start
from another shell with higher ulimit:
b -n 100000 -c 200 127.0.0.1:8080/
Note that / does a lot of negotiation work (extra file opens) using
the default configuration.
It didn't take more than a minute to hit a segfault.
For some reason it seems easier to hit with my b than with standard ab
(which should do pretty much the same thing with that command-line).
b is at www.apache.org/~trawick/public_html/b.c
To build it, "grep HAVE_ b.c" and see what to define on the cc
invocation :)
(I suspect I could hit it with ab if I were more patient.
Historically b had better concurrency because it does non-blocking
connects. I don't know if 2.0 ab has been fixed to do non-blocking
connects.)
