[squid-users] Squid consumin swap

It's been a long time since I first had this problem. I have modified,
changed, erased, added configurations but I still don't see what's the
problem. My squid consumes swap until it takes it all and the service goes
down. I have 3.0Ghz processor and 512MB of RAM to offer internet service to
more than 560 users authenticated. This is the cache configuration that I
have right now.

 

cache_mem 256 MB

cache_dir ufs /var/spool/squid/cache 20480 16 256

cache_access_log /var/log/squid/access.log

cache_log /var/log/squid/cache.log

cache_store_log /var/log/squid/store.log

cache_swap_low 90

cache_swap_high 95

maximum_object_size 20480 KB

maximum_object_size_in_memory 16 KB

request_body_max_size 4 MB

 

 

the last time the squid service stopped I checked the cache.log and this is
what I get:

I'm concerned about the swap maxsize. I don't know if I'm wrong but it says
that I have 20GB when I only have 1GB of swap available in the system
(RedHat Enterprise Linux 4).

 

Please I need some feedback if you can help me solve this. I don't know what
to do. My squid is consuming too much swap!!!

 

thanks
