Yes, 2.4Stable1.

Wow, 1.8 GB is big! Do you have Cache Manager running? When Squid gets
this big, check the Memory Utilisation menu item. Under Allocated (KB) at
the bottom (totals), is the value close to what TOP shows?

I wonder, if there is a memory leak, would these two values become further
and further apart? In other words, does Squid know it has gotten that big
or not?

I'm pretty new to this so I don't know what to expect from Squid as far as
memory utilisation goes. Mine hasn't grown out of control yet so perhaps
I'm jumping the gun. I got nervous when I saw it suddenly jump from 220 M
to 500M in one day! Before that it took about 2 weeks to climb to 220 M.

I made some other changes to my config today including upgrading to the
latest tar ball and running the dlmalloc option. We'll see what that
does.
