Hello all,
We are trying to get Apache 1.3.12 working with Tomcat 4.0.4 and are using
the warp(1.2.0-dev, i think) connector. We are using solaris8, and Apache
and Tomcat are on different servers. But, whenever we try to connect to / or
/examples, we get segmentation faults in apache. Something's not right, and
we have been spent over a week trying to get Apache to work with Tomcat
using the warp connector. If we can't get this working in about a day or so,
we will probably be going for NewAtlanta's ServletExec. The boss doesn't
mind paying if he can get support, I guess... so, here's our config and the
errors we're seeing:
We've gotten the connector compiled, and included in Apache like this:
LoadModule webapp_module libexec/mod_webapp.so
AddModule mod_webapp.c
<VirtualHost 10.101.10.100:17890>
ServerName server.ourcompanyname.com
... other directives, including a DocumentRoot... ....
WebAppConnection warpConnection warp 10.101.10.98:8181
WebAppDeploy examples warpConnection /examples/
WebAppDeploy cirqit-tom warpConnection /
WebAppInfo /webapp-info
</VirtualHost>
We also have other virtual hosts in apache that are on different IP
addresses, and different ports. 10.101.10.100:17890 is the only host with
WebApp directives. The other hosts are all using ServletExec as a servlet
engine. (So, of course, that means, we also have mod_servletexec loaded!)
In Tomcat, we have the Http and mod_jk connector tags commented out, and
only the webapp one enabled. here's what it looks like:
<Service name="Tomcat-Apache">
<Connector className="org.apache.catalina.connector.warp.WarpConnector"
port="8181" minProcessors="5" maxProcessors="75"
enableLookups="true"
acceptCount="10" debug="0"/>
<!-- Replace "localhost" with what your Apache "ServerName" is set to
-->
<Engine className="org.apache.catalina.connector.warp.WarpEngine"
name="server.ourcompanyname.com" defaultHost="server.ourcompanyname.com"
debug="1" appBase="webapps">
<!-- Global logger unless overridden at lower levels -->
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="apache_log." suffix=".txt"
timestamp="true"/>
<!-- Because this Realm is here, an instance will be shared globally
-->
<Realm className="org.apache.catalina.realm.MemoryRealm" />
</Engine>
</Service>
Apache error log gets these whenever I make a request to /:
[Wed Sep 4 17:30:40 2002] [notice] child pid 13483 exit signal Segmentation
Fault (11)
[Wed Sep 4 17:34:34 2002] [notice] child pid 13513 exit signal Segmentation
Fault (11)
Tomcat's apache access log has this in it:

So, what seems like it could be wrong? Is our actual mod_webapp.so screwed
up? Is it just our configuration? What could be causing these segfaults in
the connector? Should we just forget mod_webapp and try mod_jk? Is it a
possible conflict with ServletExec, which is running on the other virtual
servers in apache?
Any assistance is highly appreciated!
