Hello, On a server that has a very dynamic set of iptables rules (used for traffic accounting), I occasionally see a 'iptables -D ...' command in the session start or session end scripts return: iptables: Resource temporarily unavailable I've checked the source code for any occurance of EAGAIN (which matches this message) but there isn't any. Can someone explain in which case iptables would get a EAGAIN error? This is a -D (delete rule) command, not -L, so I don't think that it can be DNS-related, can it? Thanks in advance for any hint, Greets, _Alain_
