Thanks for Your reply,
As you sugested now I have squid 2.6 STABLE 17 and the memory usage is the
same as it was before:
top - 21:59:22 up 4 min, 1 user, load average: 0.01, 0.06, 0.02

Hello,
I have squid server running on Linux Debian Etch. Squid Version
2.6.STABLE5
First step is upgrade to the latest 2.6 STABLE17 from unstable. There
have been a lot of improvements made since stable5.
Amos
is using LDAP group authentication based on Win2003 domain controller.
The hardware configuration is:
IBM xSeries 336 with one XEON 3.4GHz, 4GB RAM, 2xHDD SCSI 146GB 15K with
RAID 1
The problem is that the squid restarts after memory leak. I tried to find
the reason, and I found that the reason is to big memory consumption by
squid parent proces which is almost the same as child memory usage which
is
the main cache proces.
Below is the top informations about memory usage:
top - 22:41:04 up 1 day, 3:55, 1 user, load average: 0.00, 0.00, 0.00

42.5 4175 root 25 0 1456m 1.4g 404 S 0 0:00.10 squid
This are the main squid.conf entries:

icp_port 0

auth_param basic credentialsttl 1 minute
no_cache deny QUERY
cache_mem 48 MB

Try reducing:
maximum_object_size 90000 KB
minimum_object_size 0 KB
request_body_max_size 900000 KB
cache_dir ufs /var/spool/squid 8192 128 256
cache_dir ufs /var/spool/squid 8192 16 256
cache_replacement_policy heap LFUDA
cache_store_log none
access_log /var/log/squid/access.log
forwarded_for off
delay_pools 1
delay_class 1 1
delay_access 1 allow all
delay_parameters 1 74000/74000
Is this memory usage by parent proces right ?
How can I change it ?

Tomasz Krawczyk

Please use Squid 2.6STABLE17 or 3.0STABLE1.
There are serious security advisories out on all earlier releases.
