the uptime at the moment is only 4h - so I can only report the actual 
output:

netstat -mss && vmstat -m|grep mclpl

1497 mbufs in use:
         1110 mbufs allocated to data
         387 mbufs allocated to packet headers
34 calls to protocol drain routines

vmstat: Kmem statistics are not being gathered by the kernel.
mclpl       2048     1578    0      938   408    74   334   398     4   512    7
