I don't understand what you are attempting nor what error you think you might be experiencing.

Ironically, the only part of your post that I decipher are the parameters that you find strange.

Your message queue is 4140 bytes long, the number of messages on the queue is zero, and the time of the last message send is... well, you never have sent a message to this queue.

Why is that strange? What is pushing and pulling? Do you mean push/pop as with a stack? How do you think you can do that? What does disabled mean? How do you approach a queue?

msg_send - Send a message to a message queue

SYNOPSIS
bool msg_send (resource $queue, int $msgtype, mixed $message, [bool $serialize = true], [bool $blocking = true], [int &$errorcode]) DESCRIPTION
msg_send(3) sends a $message of type $msgtype (which MUST be greater than 0) to the message queue specified by $queue. PARAMETERS
o $queue - o $msgtype - o $message - o $serialize - The optional $serialize controls how the $message is sent. $serialize defaults to TRUE which means that the $message is serial- ized using the same mechanism as the session module before being sent to the queue. This allows complex arrays and objects to be sent to other PHP scripts, or if you are using the WDDX serializer, to any WDDX compatible client. o $blocking - If the message is too large to fit in the queue, your script will wait until another process reads messages from the queue and frees enough space for your message to be sent. This is called blocking; you can prevent blocking by setting the optional $block- ing parameter to FALSE, in which case msg_send(3) will immediately return FALSE if the message is too big for the queue, and set the optional $errorcode to MSG_EAGAIN, indicating that you should try to send your message again a little later on. o $errorcode - RETURN VALUES
Returns TRUE on success or FALSE on failure. Upon successful completion the message queue data structure is updated as follows: $msg_lspid is set to the process-ID of the calling process, $msg_qnum is incremented by 1 and $msg_stime is set to the current time. SEE ALSO
msg_remove_queue(3), msg_receive(3), msg_stat_queue(3), msg_set_queue(3). PHP Documentation Group MSG_SEND(3)
