Here are some commands you may find useful for monitoring memory usage:

• It’s possible to view the memory usage with the command: free
• How much memory is using a process with the command: ps
• With the command top you will have a view, in real time, of the running processes, the CPU percentage usage, the memory usage and the total load on the system

openvpn je glavni potrošać memorije

da pokušam sa brisanjem nepotrebnih kernel modula

root@router-wan-sa-1:/tmp# rmmod switch-robo 
root@router-wan-sa-1:/tmp# rmmod switch-core 
root@router-wan-sa-1:/tmp# rmmod diag
root@router-wan-sa-1:/tmp# rmmod ipt_unclean 

ne vidim ne zehru promjene u stanju memorije

vidim ove nfs module njih bih trebao izbaciti takođe iz samog image-a

root@router-wan-sa-1:/tmp# rmmod nfs
root@router-wan-sa-1:/tmp# rmmod lockd
root@router-wan-sa-1:/tmp# rmmod sunrpc

stanje ram-a je sada 94%

ne znam šta je i koji ga paket instalira ali pretpostavljam da i ovaj ipt ne trebam

root@router-wan-sa-1:/tmp# rmmod ipt_layer7

treba sve ove ipt-ove pročešljati

šta od toga treba šta ne

sada ima 98% zauzeće ram-a

openwrt forums: [Howto] Enable swap

pokušao na /tmp prebaciti

root@router-wan-sa-1:/tmp# scp hernad@192.168.45.153:~/Desktop/*trx .
hernad@192.168.45.153's password:

ali se router smrzao ovdje

iako je on živ

hernad@nmraka-1:~$ ping router-wan-sa-1

ali očigledno nijedna nova operacija ne može da se realizuje

ugasi upali na prekidaču ... ništa mi drugo nije preostalo

vidio ovo

uradio /etc/init.d/openvpn restart

Mem: 12148K used, 2140K free, 0K shrd, 816K buff, 3108K cached
CPU:   0% usr   3% sys   0% nice  96% idle   0% io   0% irq   0% softirq

a domaloprije je bilo slobodnih cca 30 KB ?!?

da da openvpn je jedač memorije definitivno

kada se konekcije sa klijentima ostvare, mem opet padne na cca 340 KB free

ali da nema openvpn neki memory leak ?!

mislim da i ovi imaju sličnu konfiguraciju i sličan problem

ali ni ovo nije pravilo

evo sad ulovio, iako su sve openvpn veze aktivne

Mem: 13320K used, 968K free, 0K shrd, 736K buff, 2516K cached
