Forgot to explain my example :) In the Log file, "...added successfully to SHM..." means that shm_put_var() returned true. But the next time I call shm_get_var(), I get the following error: "variable key ... doesn't exist in bbb.php4 on line ..." Giancarlo. ------------------------------------------------------------------------ [2002-01-14 12:19:45] gik at zap dot cl I've been experiencing the same problem on a dual cpu server, even with PHP 4.1.1. Sometimes occurs that shm_put_var() doesn't correctly write data to SHM but returns true, and as I manage an array of online users in SHM, I have noticed that all users sometimes are dropped off. I also check semaphores before writing to SHM. 16:44:41 User aaa added successfully to SHM. (8104 bytes written) 16:45:54 User bbb added successfully to SHM.

(8206 bytes written) 16:49:29 User ddd added successfully to SHM.
