Hi all,
- OpenBSD 4.0 (build on snap from aug. 28 2006 23:10)
- i386
- 'netstat -m', 'top' and 'dmesg' below.
I've just rebuild one of my BGP routers and I'm having a real bad
memory/performance issue with this box.
(yes, Im running -current in production due to a Intel Pro/1000GT Quard
card I've had to put in the box; only supported in -current).
The box seems to choke on <whatever> once and awhile and the problem
seems to be memory related.
If I e.g. ping one of my peers, I see this:
...
ping: Could only allocate a receive buffer of 8191 bytes (default 65535)
...
Do not like the sound of that, so I did a netstat -m:
4517 mbufs in use:
4500 mbufs allocated to data
12 mbufs allocated to packet headers
5 mbufs allocated to socket names and addresses
4495/5886/6144 mbuf clusters in use (current/peak/max)
12988 Kbytes allocated to network (77% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
...
I've made a sysctl change:
net.inet.ip.ifq.maxlen=250
but resetting that to 50 (standard) does not help.
Can anybody point me in the right direction ?
Any help is appreciated.
