Description:
------------
On my developement-system (FreeBSD 5.1), msg_receive doesn't block until a new message arrives, even if MSG_IPC_NOWAIT is not passed to flags. msg_receive will return immediately, returning false.

Reproduce code:
---------------
while (true) {
   $rcv = msg_receive ($key, 0, $msg_type, 65536, $msginfo, true, 0);
   var_dump ($rcv));
}

Expected result:
----------------
The script should block until msg_receive returns true

And does it emit a warning or error message?

Kernel errno was 13 -> 62 #define EACCES 13 /* Permission denied */
Doubleckecked permissions, now working.
Sorry.
