Hi folks,
I'm having (again) a problem with network buffers. I'm running a
router/firewall/bandwith controller in a PIII-1GHz, 128MB with three 3COM
3C-905B NICs.
In one of these NICs I have 10 IP addresses (i don't know if it
matters).
My kernel is compiled with NMBCLUSTERS 16384.
The problem is that I have a certain client (that uses this router as
his gateway) that suddenly stops to access the router. When I try to ping
it, i get the following response:
PING 123.123.123.1 (123.123.123.1): 56 data bytes
ping: sendto: No buffer space available
ping: sendto: No buffer space available
So I tried to change the client's IP Address, and it worked, though the old
IP continued having the same problem. OK. But after some hours, the problem
appeared with the new IP Address, and the old one stopped.
I'm having to change the client's ip address to have him connectiong with my
router. This happens ONLY WITH THIS CLIENT. I tried to change the WaveLAN
card and PCI adapter (that's the way he connects with the router) but the
problem continues.
That's the output of my `netstat -m`:
397/720/10240 mbufs in use (current/peak/max):
397 mbufs allocated to data
394/658/2560 mbuf clusters in use (current/peak/max)
1496 Kbytes allocated to network (19% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
Can anyone help??
Thanks in advance
