hi all , i want to mention a strange problem in squid . im using smp with squid 3.3.9 this problem is as follow : squid start fine , after about 7-10 days , log files stop , squid hanged , but wccp still active with cisco router , and as a result the users complain from "NO Iinternet access" it seems kill the http traffic but before that hang occurs , i note that just * kid3* is restarted many times i see it in cache.log , im not sure if that is natural !! i mean that kid3 may restarted many times and squid still running *(not sure if this has realtion to problem before it occurs )* note that kid3 is not a disker process . agian , the hang is on squid only , not on system as all . wish to help , what to monitor and how troubleshoot before and after the hang occurs . i have 8 G ram , i have 8 cores on my machine . my options : Squid Cache: Version 3.3.9 configure options: '--build=i486-linux-gnu' '--prefix=/usr' '--includedir=/include' '--mandir=/share/man' '--infodir=/share/info' '--sysconfdir=/etc' '--enable-cachemgr-hostname=drx' '--localstatedir=/var' '--libexecdir=/lib/squid' '--disable-maintainer-mode' '--disable-dependency-tracking' '--disable-silent-rules' '--srcdir=.'
