Your shared memory implementation is buggy in 4.1.1. You can attach a shmem segment, but you can not detach it.

This is a real bug.

If I try to detach an existing and valid shmem segment, I get this:

Warning: The parameter is not a valid shm_indentifier in ...

I am using shared memory in a production environment at it is very important that someone gives me a feedback.

There were no problems with shmem on php4 but this time its buggy.

If you are talking about --with-sysvshm shared memory
there was a change of parameters for some functions
like shm_remove. It use to take shm_key as the argument,
while it take mem_id now.

The documentation is updated and should give you
enough info to fix the problems.

If this does not solve your problem,
please reopen the bug report with some more info.
