Re: [squid-users] Valgrind results on 3.2.1

Some new stuff has been logged by valgrind overnight- it's at the bottom of this e-mail. Looks like mostly dupes but I see some that might be new.

However I still don't see any accounting for the amount of leakage I'm seeing. Right now, squid on one of my servers is using a whopping 5GB of memory, yet when I do mgr:mem on it, it only tells me that the total of all allocations is about 600 MB.

How can I find out what all those allocations are coming from, since mgr:mem doesn't seem to have any accounting of them?

Thank you
