Apache2 mod_jk segfault

[Neil Wilson <ne...@dcdata.co.za>]

Hi guys,

I'm getting a segmentation fault in my apache2 error.log and I think 
it's related to my mod_jk.

When I restart apache2 I see the following errors.

[Thu Oct 25 11:14:33 2007] [error] (13)Permission denied: 
apr_global_mutex_lock(jk_log_lock) failed
[Thu Oct 25 11:14:33 2007] [notice] child pid 12242 exit signal 
Segmentation fault (11)

Below are my current versions.

apache2-prefork-2.0.59-1.1
mod_jk/1.2.14

I can't upgrade the packages, they all came prepackaged as RPMS with my 
current Scalix version and I can't be sure that if I upgrade some of 
them that the Scalix will continue working.

If I disable the following configuration file 
/etc/apache2/conf.d/scalix-tomcat-connector.conf then apache2 starts 
responding again, so it's definitely something to do with this.
Below is the content of this conf file.

<Location />
   AddOutputFilterByType DEFLATE text/xml text/html text/css
   AddOutputFilterByType DEFLATE application/x-javascript
</Location>

<IfModule mod_jk.c>
JkLogLevel          info
JkLogStampFormat   "[%a %b %d %H:%M:%S %Y] "
JkOptions          +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"

Include /etc/opt/scalix-tomcat/connector/jk/instance-*.conf
Include /etc/opt/scalix-tomcat/connector/jk/workers.conf

</IfModule>
<IfModule mod_jk.c>
JkLogFile     /var/log/apache2/mod_jk.log
</IfModule>


Below is the content of ..jk/instance-mail.conf

Include /etc/opt/scalix-tomcat/connector/jk/app-mail.*.conf
JkWorkerProperty worker.mail.type=ajp13
JkWorkerProperty worker.mail.host=mail.northcity.co.za
JkWorkerProperty worker.mail.port=8009
JkWorkerProperty worker.mail.socket_keepalive=1

Sorry for the long post, but I'd rather give too much info than too little.

Thanks, any help will be most appreciated.

Regards.

Neil.

True, it's only the web app part of scalix that's broken, so hopefully 
it won't interfere with anything else if I upgrade it.

Thanks.

Well, it isn't working now so what have you got to lose? I'd try the
latest mod_jk and see what happens. You can always go back to 1.2.14.
