Thank you for your reply. shmop_open($sem_key, "w", 420, 1) creates the same error message: ----------- [07-Dec-2007 12:34:23] PHP Warning: shmop_open(): unable to attach or create shared memory segment in ... [07-Dec-2007 12:34:23] PHP Stack trace: [07-Dec-2007 12:34:23] PHP 1. {main}() ...test.php:0 [07-Dec-2007 12:34:23] PHP 2. shmop_open(1996497860, 'w', 420, 1) ... test.php:13 ------------ Now PHP (or whatever) doesn't change the value 420. I already googled for the message, but could not find any hints. Regards, Rolf.
