Hi,
I have network server running on OpenBSD 4.3. Kernel was patched and
recompiled with changed amount of queue for hfsc and cbq to 768.
This machine has 3 interface, two external and one internal.
On each interface i have hfsc queing active. On server i have DHCPD server,
DNS (bind), PF+queing, Postfix + sasl + postgrey + clamd for small group of
users.
Server working for 100 hosts.
My problem: In my logs i'm getting following message:
dhcpd: send_packet: No buffer space available
I tried to change my NIC, change values for sysctl, but this did not help
me... Someone had similar problem ?
Below I included additional information which can help to set the cause of
problem
Thank You!
