In my SLES8, in a Pentium III 850 Mhz with 256 Mb in RAM, 3 Ethernet with a lot of IP and have No buffer space available and some disconnecting in the more day traffic.


In the /var/log/messages i have some like this:

I can't ping. I need to restart the net but the system has the problem again in few minutes. If is a weekend or night, (less people working), I don't have problem.

The network configuration is this:

The lo is good. I was cheking in Suse Support and speak about it.

The free is:

servidor:/var/log # free
total used free shared buffers cached
Mem: 253784 247456 6328 0 20432 59144
-/+ buffers/cache: 167880 85904
Swap: 955780 40596 915184


In the day is a big problem!!!

Any ideas?
