Message queues not working properly PHP -> C [message #179582]

Hello all,

I've got a php script that needs to send out some info to a c script
(already running). Somehow when php sends out through a message queue it
looks like it copies the previous message (send by php or c) and copies
it's own message over it with the previous message still visible if it
is longer than the next php message. No messages are lost though, only
copied and overwritten.

So see below the terminal output. First we send three time "Hi" (the
quotes are added by the c app). Then three time "Hai hai" and the last
time "Hi".

Adding \r, \n or \n\r does not help

Can someone tell me what's going wrong here? Communication between php
-> php goes without error, same goes for c -> c and c -> php. But php ->
c not.

The php script is copied below.

Thanks in advance, Maarten

if (!msg_send ($msg_id, 1, "Quit", false, true, $msg_err))
echo "Msg not sent because\n";
?>
