Hi,
It looks like I have a race condition on HPUX with apache 2.0.59. Here's
what I see in the error logs:
[Tue May 29 07:41:16 2007] [notice] child pid 27662 exit signal Illegal
instruction (4)
I was able to reduce the httpd.conf file to a simplified form in order to
reproduce this error. Here's my file:
Listen 10.37.74.21:80
User nobody
Group nogroup
DocumentRoot "/usr/local/httpd/htdocs"
<Directory />
Options FollowSymLinks +Includes
AllowOverride AuthConfig Limit Options
<LimitExcept GET POST HEAD>
Order deny,allow
Deny from all
</LimitExcept>
</Directory>
LoadModule rewrite_module modules/mod_rewrite.so
ErrorLog logs/haha_log
RewriteEngine On
RewriteLog /usr/local/httpd/logs/rewrite.log
RewriteLogLevel 9
RewriteMap balancer rnd:/usr/local/data/etc/ei.map
RewriteMap lowercase int:tolower
RewriteRule "^/ei/(.*)" - [E=EI_CHECK:1]
RewriteCond %{ENV:EI_CHECK} ="1"
RewriteCond ${lowercase:%{HTTP_COOKIE}} ut=[a-z0-9]+[02468acegikmoqsuwy];
[OR]
RewriteCond ${lowercase:%{HTTP_COOKIE}} ut=[a-z0-9]+[02468acegikmoqsuwy]$
RewriteRule "^/ei/(.*)" http://${balancer:LB2}/$1 [L,P]
RewriteRule "^/ei/(.*)" - [E=BIS:set]
RewriteCond %{ENV:EI_CHECK} ="1"
RewriteCond %{ENV:BIS} !=""
RewriteRule "^/ei/(.*)" http://${balancer:LB1}/$1 [L,P]
RewriteCond %{ENV:EI_CHECK} ="1"
RewriteCond %{ENV:BIS} =""
RewriteRule "^/ei/(.*)" http://${balancer:LB1}/$2 [L,P]
The ei.map file looks like this:
LB1 img01.joedog.org:80
LB2 img02.joedog.org:80
The condition occurs when I assign values to ENV variables with
mod_rewrite then I try to access those variables. This configuration works
on other platforms. The child process dies on HPUX.
Any insights?
Jeff
