[Php-java-bridge-users] Having some trouble with hung apache children and an older version of java-bridge

[<php...@li...>]

I found some discussions from earlier last year that that discussed a 
problem identical to what I'm getting:

https://issues.apache.org/bugzilla/show_bug.cgi?id=43966

http://sourceforge.net/mailarchive/forum.php?thread_name=1205435208.2906.45.camel%40kukac&forum_name=php-java-bridge-users

It wasn't clear to me what the resolution was other than patching java.c.


Is this just an issue with the older method of running JavaBridge.jar 
under apache instead of in its own process?

Hi

please see our FAQ "How do I enable the Java extension in my php.ini file?"
(http://php-java-bridge.sourceforge.net/pjb/FAQ.html)

I'm confused how that is relevant to my question. I must not have 
explained my problem sufficiently in my previous post.

We are running 4.3.3 fine now. We were previously running a version 
around 4.0.1.

When we upgraded to apache 2.2.9 using the same java.so we found that 
apache processes were hanging and not exiting. I got a backtrace from 
them that looked like:

This seems to be identical to the discussion I previously referenced.

Things seem to have changed significantly in the 5 stream. We will 
change our code to work with the new stream, eventually but it doesn't 
seem trivial.

Hi,


> java.so

Remove it. 

Whether or not it's a PHP bug or a bug in Apache, I don't care. Simply remove the Java extension and use the pure Java PHP/Java Bridge instead.

The java.so is unsupported since PHP/Java Bridge version 3.2.1.  Please see the NEWS for details.

Hi again,

not really. Version 4.x was a transition towards a pure Java implementation (PHP/Java Bridge 5).

Version 5 has a flag which enables backward compatibility (define ("JAVA_PREFER_VALUES", true)). See our API documentation for details.
