Re: [Php-java-bridge-users] cli processes hang around sometimes

do these processes still exist? Can you do a "ps auxwf" please?

I've just looked at the code. The JVM is started in the MINIT procedure and terminated (via kill
SIGTERM, kill SIGTETM, kill -9 ...) in the MSHUTDOWN procedure. So if the PHP executable hangs,
this means that the PHP MSHUTDOWN procedure hasn't been called (which used to happen with recent
PHP binaries, when called with a zero-length PHP script); it means that there is a bug in your PHP
CLI binary. 

Please either do not use this PHP CLI binary or start Java as an external process.

Please see the README or INSTALL.* documents from the binary download. Or this link
http://www.ibm.com/developerworks/aix/library/au-javaphpaix5/ for a detailed description how to
install the bridge.

As I've said. If you ask PHP to start a JVM attached to it and the JVM does not terminate
(probably due to a bug in the PHP), PHP will hang. Please see the documentation that comes with
the PHP/Java Bridge download to see how to change it.
