Wow. I just spent some time searching on this, because it appears to be
using nearly 1 GiB of memory on my system. I was investigating why I
have swap memory being used (407,548k of it!) when my system shouldn’t
be swapping out to disc. I am wondering if this might be some of the
problems that have been reported with GAIM crashing. I know that I run
it all the time, and isn’t there a limitation on how large a process’
memory space can be? That might be the cause of some of the stranger
sig11 deaths that have been reported. Anyway, “top” reports the
following on my system. The output from top, by the way, is organized
by the “VIRT” column:

This might be an obvious question, but I cannot see why any of these
processes are using this much memory. I know that some of this memory
(as I understand it, the memory in the SHR column) is shared with other
processes for things like shared libs and the like. Assuming that this
is correct, there is 951-12=939m of system resources that GAIM is using…
Is there a resource that anyone knows of, by the way, for finding out or
reasonably estimating what a process’ memory footprint *should* be? I
have a system that has 876 MB of RAM, and it should be very happy with
the things that I do on it in that configuration. Granted, Windows
Vista is even *more* memory intensive with just its core system and runs
like lead, but that’s neither here nor there. I am going to Google some
more on this one (re estimating reasonable footprints), but if someone
knows the answer to that, I would appreciate that, too.
