Re: [squid-users] cache filled up ... why?

It (squid) estimates how much space it has by taking the
store_avg_object_size and multiplying that by the number of objects...

your objects size is obviously much larger than the predefined average
(13kb), mine is to... just crank that value up a bit, like 20-25kb and you
won't run out of space...
