weiss wer damit was anzufangen? das zuwenig speicher in der kiste ist, weiss ich (lässt sich aber nicht erweitern)
und warum benutzt er nicht einfach swap?

kernel ist 2.6.38-r1-gentoo, ich werde diese woche mal den kernel updaten, vielleicht bringt das was.

das system läuft trotz den meldungen übrigens 24/7 ohne weitere probleme

update : scheint ein memory-leak im ath9k modul zu sein (laut google)
würde auch die sache mit dem swap erklären, glaube kaum das speicher, welcher von modulen benutzt wird,
ausgelagert werden kann

werde wohl erstmal ein kernel update versuchen

also ein update auf 3.0.6 hatte erstmal nichts gebracht

aber in diesem thread
https://forums.gentoo.org/viewtopic-t-899896.html
habe ich den tip bekommen die network-puffer zu erhöhen

mit den werten

Code:

net/core/rmem_max = 8738000
net/core/wmem_max = 6553600

net/ipv4/tcp_rmem = 8192 873800 8738000
net/ipv4/tcp_wmem = 4096 655360 6553600

vm/min_free_kbytes = 65536


habe ich gestern gut 20GB vom router gezogen, und die fehlermeldung taucht nichtmehr auf
