As some of you may remember, I reported a problem with MBUF leakage
on a FreeBSD-stable system running an Emerging Technologies ET5025
card. After Dennis' indication that the problem was FreeBSD-stable
and rather strong suggestion that I need to be running 2.1.0, I
have reinstalled this system running stock FreeBSD-2.1.0. The
problem still exists and can be directly related to activity over
the 56K connection. A much busier system of same kernel vintage
without the ET drivers hovers at around '75 mbufs in use' after
several days of uptime. The system will reach it's max of 4096K
after about 48 hours of uptime and eventually reboot. I'm at a loss
for how to track this down and would heartily welcome more
productive suggestions.
After:
5:12PM up 3:24, 1 users, load averages: 0.00, 0.00, 0.00
=> netstat -m
792 mbufs in use:
788 mbufs allocated to data
2 mbufs allocated to packet headers
1 mbufs allocated to protocol control blocks
1 mbufs allocated to socket names and addresses
349/354 mbuf clusters in use
807 Kbytes allocated to network (98% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
=> dmesg
