Just a mee too on this one. I'm running two NFS servers on 5.2.1-RELEASE (with the old mbuf code obviously), and I see the problem with leakage here. Don't know a way to reproduce it yet, but it happends over time. This happends both on a UP and a SMP machine. After more than a month of uptime, the mbuf map starts to get eaten up. Is there any way to look at the mbuf cache while the system is running to see what is in there? Example: host1: up 76 days mbuf usage: GEN cache: 1962/4256 (in use/in pool) CPU #0 cache: 22742/23040 (in use/in pool) Total: 24704/27296 (in use/in pool) Mbuf cache high watermark: 512 Maximum possible: 51200 Allocated mbuf types: 24670 mbufs allocated to data 31 mbufs allocated to packet headers 3 mbufs allocated to socket names and addresses 53% of mbuf map consumed host2: up 23 days mbuf usage: GEN cache: 1/768 (in use/in pool) CPU #0 cache: 254/608 (in use/in pool) CPU #1 cache: 0/512 (in use/in pool) CPU #2 cache: 0/512 (in use/in pool) CPU #3 cache: 3/512 (in use/in pool) Total: 258/2912 (in use/in pool) Mbuf cache high watermark: 512 Maximum possible: 51200 Allocated mbuf types: 258 mbufs allocated to data 5% of mbuf map consumed Cheers, Frode Nordahl > Cheers, > Bosko > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to > "freebsd-current-unsubscribe@freebsd.org"
