[squid-users] Memory usage of squid parent proces the same as child

Hello,

I have squid server running on Linux Debian Etch. Squid Version 2.6.STABLE5
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
Tasks: 112 total, 1 running, 111 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 99.8%id, 0.2%wa, 0.0%hi, 0.0%si,
0.0%st

Swap: 2650684k total, 0k used, 2650684k free, 165420k cached

This are the main squid.conf entries:

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 ?
