[squid-users] squid -k rec , seems has problem with ram leakage ?

Hey Ahmad,

I’m not sure I understand what 100 instances of squid means?
Are you talking about 100 workers?

hi amos 

i didnt use the version 3.5.22

 but long time I’m using the 3.5.22 and its fine 

the new thing is I’m using like 100 squid instances .

and  hourly i have cron to change and update squid 

so i just make rec option instead of having session drop .

i don’t have exact mount of statistics to tell you 

but say i have 32 G ram 

if i run 100 squid instances it take about 16 G ram .

if i keep run the cron hourly by time say daily 12 times ( every 2 hours) 

and after 1 week i go to server to see free ram using :

free -m command

i see the free ram be like 5 G free , while I’m supposed to see the free as 16 G

if i kill all instances and run it again 
the free is 16 G


so as i said , by time , by doing many -k rec OPTINOS , there is something not ok either os or squid I’m not sure .

is there any tuning can i do in squid ?

or os ? I’m using centos 6 64 bits and may be option in sysctl to play with ?

here is my config file :
dns_nameservers 8.8.8.8
dns_v4_first off
