Previous Comments: ------------------------------------------------------------------------ [2002-10-10 06:47:53] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip ------------------------------------------------------------------------ [2002-10-10 00:25:33] [EMAIL PROTECTED] I have just compiled and tested this on RH7.2 ans 4.2.4-dev and the same behaviour still exists. If you run php -v enough times (in my case 58 times) you end up with a whole bunch of semaphore arrays that have not been cleaned up and php dying when run fit rom the command line with: $ php -v Content-type: text/html PHP Fatal error: Unable to start session mm module in Unknown on line 0 ------------------------------------------------------------------------ [2002-08-12 09:51:30] [EMAIL PROTECTED] IIRC, this was fixed someday... if it works with 4.2.2 than it's no longer a bug. Please try a (non-STABLE) snapshot from http://snaps.php.net and reopen this report if the problem still persists. ------------------------------------------------------------------------ [2002-08-12 00:34:48] [EMAIL PROTECTED] I've been contacted by a php user in the wild who told me that by simply issuing 'php -v', a semaphore that php opens for session management is not closed on exit. This becomes bad news because the ipc system on linux is a global resource and not based per user, so it's possible for a local user to DOS the box by running php -v repeatidly. [test@alpha3 test]$ ipcs > l [test@alpha3 test]$ php -v Content-type: text/html 4.1.2 [test@alpha3 test]$ ipcs > ll [test@alpha3 test]$ diff l ll 9a10,11 > 0x00000000 65538 test 600 1 > 0x00000000 98307 test 600 1 I tried to trace this out between 4.1.2 and 4.2.2 (4.2.2 does not exhibit this behaviour) but I can find no obvious differances in the codepaths between versions. This behaviour seems to be present all the way back to 4.0.6 from the little additional checking I made.
