[squid-users] cache/mem ratio ok but swap grows

My swap seems to just grow and grow until I restart squid.

Why?

I want to grow my cache store another 40-50 gig.

Is this safe?

Ram is always maxed out

I know about the mem/cache size ratios and I'm well within bounds

All other stats look fine

Here are my mrtg stats

You can see where I've restarted squid and the swap and ram clears.
