Hi,
I have not seen the no buffer space message, but I have been getting
this collapse of network services. I will be telneted into one of my
machines and all of the sudden I get no response to anything I type, no echo
either. After a couple minutes the telnet session disconnects. If I ping
the machine in question from outside the network it is still alive. After
5-10 minutes I can connect by telnet again and all is well for some time.
dmesg shows no messages logged during the outage time.
Please let me know if you figure this one out and I will do likewise.
Cheers
Charlie Reese
