Errno::ENOMEM (but now with no reason)

["Iñaki Baz Castillo" <ibc@aliax.net>]

Hi, sometimes hen I change the name of the queue I get this error:

  Cannot allocate memory - mq_open (Errno::ENOMEM)

It would make sense if I haven't unlinked previous mqueues but I did it. In 
fact I mount /tmp/mqueue to display the existing mqueues and I can't see the 
previous one (as I deleted it with "POSIX_MQ.unlink(name)".

More data:
- The user running the command has "ulimit -q => 819200".
- Queues default values (prox/sys/fs/mqueue) are:
  - queues_max = 256
  - msgsize_max = 8192
  - msg_max = 50

So 50x8192 = 409600 < 819200.

Even more annoying: Being root I set "ulimit -q unlimited" and cannot create 
the queue (being /tmp/mqueue empty, for sure I unlinked the queue previously).
But I become a normal user "ibc" (the user who created the first queue) and I 
*can* create the mqueue!!

These days I've detected it randonly and I'm very confused. Do I miss 
something?

Regards.
