Qual a solução para esse problema no squid 2.6?

Estou tendo sérios problemas com a falta de memória no squid 2.6!

Estou usando:

Kernel:2.4.31 Slackware

Squid -v: Squid Cache: Version 2.6.STABLE4
configure options: '--prefix=/usr/local/squid' '--enable-delay-pools' '--enable-cache-digests' '--enable-arp-acl' '--enable-default-err-language=Portuguese' '--enable-storeio=aufs,coss,diskd,null,ufs' '--enable-removal-policies=heap,lru' '--enable-linux-netfilter'.

*cache_mem 30 MB
*cache_replacement_policy heap GDSF
*memory_replacement_policy heap GDSF
*cache_dir aufs /usr/local/squid/var/cache 2500 16 256

Depois que reinicio o pc, ele volta com bastante memória free, porém essa situação de conforto não permanence por muito tempo.

Por qual motivo aparece tantos processos do squid, e porque mesmo depois que baixei o cache_men de 150MB para 30MB a memória livre continua baixa?

esse monte de processo é devido erros no squid.conf
memoria se tem livre o squid(processo) vai usar... assim como outros do linux...

axo q é esse o comando pra verificar o conf.
~# squid -k check -f /etc/squid/squid.conf

veja os logs tmb..
t+

Obrigado pela dica, mas já havia verificado a conf. com o comando acima. Não aparece nada após o comando check!

Vale a pena esclarecer: Meu servidor é um semprom 2.2 com 384MB DDR, com Squid Cache: Version 2.6.STABLE4, htb-tools (initscript for Linux CIR/MIR capabilities v0.8). Uso o dnsmasq, com htb para dividir o link entre duas redes, e complemento com o delay pools fazendo controle individual. Mesmo depois que baixei o cache-men de 150 p/ 30MB, a memória livre do Server gira em torno de 3 á 7K. É mole!
Creio que não é normal!

Segue a baixo os últimos logs do squid.
