I apoligize for adding to this, but I'm hoping to jar someones memory.
I gdb'ed the process now and the BUS error occurs in:

I hope I don't have to build a debug version of apache/mod_jk and gdb it
to find this issue.
Help?

Subject: JK 1.2.14.1 SIG BUS Error on Solaris 9
I tried to upgrade our JK modules from 1.2.12 to 1.2.14.1 and now every
Apache process crashes while processing a request with:
[Fri Sep 02 14:23:54 2005] [notice] child pid 11079 exit signal Bus
error (10)
For every request in the logs.
The config works fine with JK 1.2.12 (I can swap it in and things work)
and looks like:
==============================================
httpd.conf:
==============================================
JkShmSize 60
JkShmFile logs/jk1.shm

JkMountFile conf/uriworkermap.properties

JkRequestLogFormat "%w %V:%p%U%q %s %T"

JkMount jkstatus

-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="conf/mime.types"
-D SERVER_CONFIG_FILE="conf/httpd.conf"
What am I missing? I built jk with configure
--with-apxs=/usr/local/apache2/bin/apxs;make
I've had no problems building/running in the past with mod_jk 1.2.12. I
thought it must have been something in my config, but apparently not?
