Problem sometimes Freebsd crash

Hi friends,

My name is Jorge, i am from Peru, excuse me for my english, I have a
server with FreeBSD 4.11-RELEASE #2 and Bandwitdh Manager (bwmgrd),
but I have many problems with it, I have rise up mbuf clusters in my
server to 16384 (It I have made in the file /boot/loader.conf), before
It was configured to 12000. Now I do not have logs about

Mar 3 20:42:57 trafico /kernel: All mbuf clusters exhausted, please
see tuning(7).
Mar 3 20:46:49 trafico /kernel: All mbuf clusters exhausted, please
see tuning(7).
Mar 3 20:46:52 trafico /kernel: All mbuf clusters exhausted, please
see tuning(7).
Mar 9 20:31:24 trafico /kernel: All mbuf clusters exhausted, please
see tuning(7).
Mar 9 20:31:27 trafico /kernel: All mbuf clusters exhausted, please
see tuning(7).

However, sometimes my server still hang, crash. I have to reboot the
server for that I work again. If I have enough memory, why bwmgrd no
use it, I do not why it said 59 requests for memory denied




There are some logs

#netstat -m

1881/9050/16384 mbuf clusters in use (current/peak/max)
20364 Kbytes allocated to network (41% of mb_map in use)
59 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines


This is report of my server memory
