In fact on another machine I manage I have: 91/528/18304 mbufs in use (current/peak/max): 90 mbufs allocated to data 1 mbufs allocated to packet headers 64/216/4576 mbuf clusters in use (current/peak/max) 564 Kbytes allocated to network (4% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines but here I've got four times the amount of RAM (0.5GB vs. 128MB). bye & Thanks av. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

No doubt about that. As I said in my first message, I *AM* willing to take an upgrade, I'd only like to have a bit more insight. In case this depends on other things, maybe it's a well-known problem, an error of mine, a misconfiguration, maybe about mbufs as you suggested, I don't think the upgrade would matter and/or help. > > >I don't have enough time to go into this in depth, but see if the > > >problem is affected by increasing the number of mbufs. > > > > Nice suggestion, how do I do that? > > Nice sarcasm; the obvious response is that you could read the manual. I had read the handbook, but found this not so clear. I also tried "man 9 mbuf", as suggested in netstat's man page, but this doesn't seem to be available on my system (why?). I was also a bit scared, since it is said to possibly lead to boot time crashes and I don't easily have physical access to the machine (which would then keep crashing and crashing, since the problem would be in the startup configuration files). I did instead produce another crash and measured mbufs usage: several seconds before the crash (I don't think it was more than a minute and a half) "netstat -m" gave: 207/496/4096 mbufs in use (current/peak/max): 203 mbufs allocated to data 2 mbufs allocated to packet headers 2 mbufs allocated to fragment reassembly queue headers 198/248/1024 mbuf clusters in use (current/peak/max) 620 Kbytes allocated to network (20% of mb_map in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines So I would guess I'm not short on these. Does this answer your suggestion or should I try anyway? If so, I'll try and do this next time I happen to be physically there (and possibly upgrade too). bye & Thanks av. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

It's more work to try to track the problem if you're using different code than (for example, I am on my) system, so upgrading is a help to the person trying to track it. I don't have enough time to go into this in depth, but see if the problem is affected by increasing the number of mbufs. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
