Segmentation fault after apachectl startssl





------- Additional Comments From trawick@apache.org  2003-04-20 13:08 -------
Mat, thanks for the strace.  Unfortunately, it is an strace of apachectl only
and not of httpd.

Adding -f to the strace invocation (as in "strace -f apachectl args") should do
the trick.

The strace output is definitely useful, but a backtrace from the segfault (i.e.,
gdb's display of the sequence of function calls up until the point of the
segfault) is usually the most valuable piece of information until the specific
problem area is identified.

e.g.,

gdb /path/to/installed/httpd
(gdb) r -DONE_PROCESS

[now it runs for a while and you see a gdb message saying it got SIGSEGV]

(gdb) where

[here is the key backtrace output]

(gdb) quit

You can also get the backtrace if Apache is dumping core:

gdb /path/to/installed/httpd /path/to/core
(gdb) where

[here is the key backtrace output]

(gdb) quit
