Bug #9427 Updated: PHP hangs when packets aren't returned when using session_start()

ID: 9427 Updated by: ssb Reported By: rargo@mcleodusa.com Old Status: Critical Status: Closed Bug Type: Session related Operating System: Linux Mandrake 7.2 PHP Version: 4.0.4pl1 New Comment: I'm not sure what PHP should do here. If an external library (mysql) does a connect and your firewall drops packages, that's a configuration problem and IMHO not something PHP should go to great efforts to try handling. I think you will find that most software behaves this way (hangs until tcp connect times out) when facing a similar setup.

Configure Command: './configure' '--with-apxs=/usr/sbin/apxs' '--with-mysql=/usr' '--with-mcrypt=../mcrypt-2.2.6' '--with-mhash=../mhash-0.8.4' '--with-ldap' '--with-fdftk' '--with-pdflib' '--with-zlib' '--with-gd' '--with-pspell' '--with-oci8' '--with-java=/opt/IBMJava2-13' '--enable-sigchild' Pretty much the default php.ini. We noticed this occurring once we put the machine inside a DMZ. If PHP tries to connect to an address that the DMZ isn't allowing, the DMZ throws the packets away and PHP sits there waiting for a response. This only happens when session_start() is called in the page. If session_start() is commented out, the normal PHP warnings appear telling me of mysql or ldap not being able to connect. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=9427&edit=1
