The apache mod_jk configuration is this one. Would you need the
workers.properties?
LoadModule jk_module modules/mod_jk.so
<IfModule mod_jk.c>
JkWorkersFile /etc/httpd/conf.d/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize
JkMount /app/* ajp13
JkMount /app ajp13
</IfModule>
These are the exact steps I have taken to build mod_jk:
./configure --enable-debug --with-apxs=/usr/sbin/apxs
make clean
make
and then as root
make install

I managed to produce a core, but it does not look like there are
any debugging info available. When I run the bt command
(using gdb -c /path/to_core), have the following:
Using host libthread_db library "/lib/libthread_db.so.1".
Core was generated by `/usr/sbin/httpd'.
Program terminated with signal 11, Segmentation fault.
#0 0x0068dbf2 in ?? ()
(gdb) bt
#0 0x0068dbf2 in ?? ()
#1 0x08506478 in ?? ()
#2 0x0068fb6a in ?? ()
#3 0xbfc5b04c in ?? ()
#4 0x00000000 in ?? ()
Would that mean the problem is not in mod_jk, or would that mean
I did not compile mod_jk in debug mode?
Thanks again for your help.
Best regards,
Nicolas
