Bug #13595 Updated: Solution for "PHP Fatal error: Unable to start session mm module in Unknown on

ID: 13595 Updated by: matt@mystile.com Reported By: plafundum@yahoo.com Status: Feedback Bug Type: Session related Operating System: Debian Sid PHP Version: 4.0.6 New Comment: Thanks to mfischer@php.net, I found the problem using strace. I had 'session.save_path' set to '/dev/null'. Why does 4.1.2 not handle this gracefully like 4.0.5, and is there any way to get a more helpful error message in this case? In case you're interested in the exact errors, I've included the errors from the strace below: unlink("/dev/null/session_mm_apache0.sem") = -1 ENOTDIR (Not a directory) open("/dev/null/session_mm_apache0.sem", O_RDWR|O_CREAT, 0600) = -1 ENOTDIR (Not a directory) unlink("/dev/null/session_mm_apache0.sem") = -1 ENOTDIR (Not a directory) Previous Comments: ------------------------------------------------------------------------ [2002-03-05 02:24:42] mfischer@php.net An other alternative would be to use use 'strace' on the apache process (make sure you start apache with -X switch), maybe you can gather where it has failed, e.g. strace -e trace=file -o output /usr/sbin/apache -X and see in file 'output' what fails. ------------------------------------------------------------------------ [2002-03-05 02:17:02] derick@php.net Can you try a snapshot from snaps.php.net? It might be fixed, if not we need feedback on that branch anyways. regards, Derick ------------------------------------------------------------------------ [2002-03-05 01:48:33] matt@mystile.com I'm seeing this problem on Slackware 8.0, when upgrading from the original mod_php.tgz package (PHP 4.0.5) to the updated version (PHP 4.1.2). I already checked, there is no 'session_mm.sem' file to remove (stopping apache automatically removes the file). So my question is, what is going on, and how do I fix it? ------------------------------------------------------------------------ [2001-11-11 12:37:22] sander@php.net So it's not a bug in PHP. Thanks & Closing... ------------------------------------------------------------------------ [2001-10-08 05:46:33] plafundum@yahoo.com Hello there, Every time I when I upgrade my Debian-install I get errors with php4-cgi. When it is invoked, php4-cgi says "PHP Fatal error: Unable to start session mm module in Unknown on line 0". I posted a message, and Peter Cech helped me out: rm /etc/session_mm.sem did the job. Cheers y'all pla. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=13595&edit=1
