Dupa cum vezi, pam_auth consuma deja peste 90% din memorie. Restul (squid,
mysql) stau sub 2%. Tot ram-ul e full iar swap-ul 1GB din 4G. Daca il mai
las, gradul de utilizare al swap continua sa creasca. Cam pe la 1G utilizare
swap, dau restart la squid si incarcarea scade imediat sub 2-3%. Uite cam asa
arata, dupa restart:
Cpu(s): 20.5%us, 6.3%sy, 0.0%ni, 71.2%id, 0.3%wa, 0.0%hi, 1.7%si, 0.0%st

deci pam_auth ia acum numai 5.7%

asa cum ai descris problema, pare un memory leak ... poate nu se mai potriveste
pam_mysql.so cu versiunea instalata de server mysql ... desi spui ca ai facut si
downgrade ... hmmm
in alta ordine de idei, prin log-urile de la squid te-ai uitat? nu cumva ai vreo
samantza de atac? vreun viermisor pe la uzeri?
