Phpbb is a bulletin board application. It may be possible that at the time perhaps it was being hit heavily. It is possible that it was set up that anyone can browse and post. You might want to look into a way to limit access to such application or think about moving up to a VPS plan if you need to have these things.

mq_notify
mq_notify(3) Library Functions Manual mq_notify(3)NAME
mq_notify - Attaches a request for asynchronous signal notification to a message queue (P1003.1b)
LIBRARY
Realtime Library (librt.so, librt.a)
SYNOPSIS
#include <mqueue.h>
int mq_notify (
mqd_t mqdes,
const struct sigevent *notification);
PARAMETERS
mqdes Specifies a message queue descriptor.
*notification Specifies a signal to be sent when the specified queue accepts a message. If the notification argument is NULL, and the
process has previously attached a notification request to the message queue with this mqdes argument, the notification
request is detached and the queue is available for another process to attach a notification request.
DESCRIPTION
The mq_notify function attaches a request for asynchronous signal notification to a message queue for the calling process. Following a
call to this function, the specified signal is sent to the calling process when the queue transitions from empty to non-empty. Two or more
processes cannot attach notification requests to the same queue at the same time.
If a process has attached a notification request and any process is blocked in the execution of the mq_receive function waiting to receive
a message when a message arrives at the queue, then the appropriate mq_receive function is completed and the notification remains pending.
When the notification has been sent, the registration is canceled. In effect, it is a one-shot notification and must be re-registered if
required.
Note that the POSIX IPC functions are not reentrant with respect to signals. For example, if your application were to use a signal to
notify it that a queue has become non-empty and then attempt to call mq_receive from the signal handler, the signal handler must reside in
a thread other than the tread that called mq_send. Otherwise, a deadlock on internal locks would occur.
RETURN VALUES
On successful completion, the function returns the value 0 (zero); otherwise, the function returns the value -1 and sets errno to indicate
the error.
ERRORS
The mq_notify function fails under the following conditions:
[EBADF] The mqdes argument is not a valid message queue descriptor.
[EBUSY] A process has already attached to this message queue for asynchronous notification, or the calling process attempted to can-
cel a request that was attached by another process.
[EINVAL] The requested signo is invalid, or the sigev_notify field of the notification structure does not equal SIGEV_SIGNAL.
