My friend told me to noticed you about problems I had with 2.4.x line of kernels. I started up from 2.4.3. Under heavy load I was getting messages from telnet, ping, nmap "No buffer space available". Strace told me it was error marked as ENOBUFS. First thought was it was my fault. I asked many people and nobody could help me. So I tried 2.4.5. It was a disaster also (should I mention few oopses?:>). Second thought was to try 2.2.19 and it was good choice. Now there are almost no messags like those above. Only thing that still happens is "Neihgbour table overflow". Some data about my Linux box: 2 x PIII 800 MHz/1024 MB; 2 x Intel EExpres 100; 3 x 3com 3c900B-Combo. Summarizing all traffic about 5mbit at the moment. # arp -an | wc -l 1018 Any more info needed? PS. It would be nice to be CCed with replies, beacause I am not subscribed to LKML. -- Michal Margula, alchemyx@uznam.net.pl, ICQ UIN 12267440, +) http://uznam.net.pl/~alchemyx/, Polish section of Linux Counter maintainer
