    service that i installed
    1. Denyhosts
    2. Squid (lusca-cache)
    3. Squid Guard
    4. bandwidthd
    5. snort
    6. cron
    7. dnsmasq
    8. ntpd




  • Squid, SquidGuard and Snort are all major resource pigs.



  • so i just leave it ???
    i need to restart it every 3 days if like that



  • Either add more memory or stop using all those packages.



  • im on 4Gb memory already..and it just used by <100 user..soon it will be more



  • I'm not experienced with those packages but it seems I heard you can tweak the configurations on Squid and maybe other packages to use less memory but by default they will just keep eating up resources. Maybe a search for configurations of Squid would be helpful.
