There seems to be a memory leak. 

After running mozilla, i am usually missing about as much ram as i had mozilla
alloted.  I believe it may have to do with the Memory used for cashe.

Worksforme build 2002082210 on Mac OS 9.

Reporter, what is your build-id ? Are you sure that Mozilla has stopped
completely ? It's possible that your windows are closed, but the menubar is
still there. We had a bug recently (last week in Mozilla 1.1.b+), where we had
to press cmd-Q twice to really close the application.

Reporter, how do you determine how many free memory you have available ?

Mac OS 9 doesn't show you this at all. In the 'About Computer', there's a
section called 'Largest Unused Block', but that's NOT the free memory in your
computer. That's the size of the largest free memoryblock, but there might be
many more blocks in memory (smaller). This is due to memory-fragmentation, and
it has been like this on the Mac since the MultiFinder (1988 ?).

When running many apps, lauching external apps (like QuickTime Player or
Acrobat), your memory might get fragmented, split up in little pieces. Even when
you quit all your apps, it's possible that you won't reclaim all the
memoryblocks, because they're still splitted up. You still have as much free
memory as before, but it's just not in a single piece. It's not very important,
as long your apps can still find 1 block, large enough for the entire
application (it has to fit in 1). After running for a very long time, it's
possible that your memory is so fragmented, that you can't launch your new
application, even after quiting as many applications as possible. There's no
other solution than to reboot. But your Mac will warn you for this, when this
happens.

Workaround: well, eh, upgrade to Mac OS X.

I'm normally running Mac OS 9 continuously on an iBook with 192MB (160 for
apps), with a reboot every 1 or 2 weeks. In the mean time, I must be launching
Mozilla at least 4 times a day, and I'll probably install a new version of
Mozilla every 2 or 3 days too. And maybe a Mozilla-crash once a day. But I'm not
seeing any memory leaks.

I don't think this is a real memory leak bug. Ethan, please see comment 2.
