I had also experienced such problem in my multi-process program, i start
several processes which shared a shared memory segment created by shm_*

or missing, my PHP version is 5.2.11, would you please to help me to
check this problem? thank you very much ~~~~ :)

Hi!
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 ..."

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. (8209 bytes written)
16:47:20 User bbb deleted successfully from SHM. (8104 bytes written)
16:47:31 User ccc added successfully to SHM. (8206 bytes written)
16:49:29 User ddd added successfully to SHM. (109 bytes written)
I offer my help to debug this problem,
Giancarlo Girardi

Have you tried this with 4.1.1?
