>Description:
	After about half an hour of uptime, all network activity ends with
	ENOBUFS. It even stops responding to ICMP ECHO, but output from
	netstat -m is perfectly normal:

87/592/524280 mbufs in use (current/peak/max):
        87 mbufs allocated to data
83/350/131070 mbuf clusters in use (current/peak/max)
848 Kbytes allocated to network (0% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines

	This problem is repetable, it occurs *every time* after about
	30 minutes of uptime, unless I decrease amount of RAM from 640 MB
	to 128 MB.

	NMBCLUSTERS and/or maxusers tuning doesn't help either. On GENERIC
	kernel, first ENOBUFS error occurs after 10 minutes of uptime.

>How-To-Repeat:
	Perfectly repetable on my hardware, occurs every time with 640 MB,
	doesn't occur on 128 MB RAM. 
>Fix:
	N/A
