AW: Max cache size reached --> squid shuts down!!! help me

Hi there,

check if you have a swap.state file and a sile swap.state.new.
The second file occours when you have 2 squids running at the same
time or due to misconfiguration. Remove the swap.state.new file
, empty the swap state ( > swap.state ) and restart the squid.
When the error still appears you must have a problem with the
cache mem. We experienced that strange error, too, on one of
our machines when using a machine with 2 Gig left on the harddisk.
The Cache already needed 2 Gig. When there was less then 2 Gig left
FREE on the device it stopped the process.

Hope this helps

Stefan

Betreff: Max cache size reached --> squid shuts down!!! help me

Okkay folks... I am running into this problem once every month or so!
I am looking for a solution!
I have configured squid to use 3 cache directories with different
size limit for each:

cache_dir /usr/local/squid/cache 100 16 256
cache_dir /data/squid/cache 2100 32 256
cache_dir /data1/squid/cache 7300 32 256

now... suddenly I notice that squid isnt running and users getting pissed
off... so I look in the cache.log and find the following:

2000/03/27 15:16:55| Starting Squid Cache version 2.2.STABLE2 for

so I do a du on the cache dir and find out it is near the limit I set
in the etc/squid.conf
file:

spider# du -sk /data/squid/
2043150 /data/squid/ <<<<<<<<<<<<<<-----------------

so I remove remove a small dir from the cache... just enough to
start squid again and
see the what the cachemgr.cgi has:

Indeed you can see that my /data/squid/cache is getting full!!!
Now I know that squid is supposed to do something when it reaches
the limit like overwrite certain old data... why isn't it doing
so?!?!?!?!why is it shutting down when the cache reaches the
maximum size I specified in the etc/squid.conf file?

this behavior is getting me frustrated.

any clues, help I appreciate it!!!

thanx,
