RE: [Pan-users] 0.13.4 memory leaks

[Chris Charlebois]

384 MB ram, 517 MB swap. Not as beefy system as yours Duncan. Maybe that's
why I encounter the problem easier.

Well, it is the VM dealing with it, sure, but that doesn't mean it's the VM 
causing the problem.

What sort of memory and swap U run, Chris & Steve?  Here, I haven't noticed 
the issue.. Base system 2.4.20 vanilla Marcelo kernel, Mandrake 9.1 Cooker, 
updated twice weekly or so, KDE 3.1 (Mdk cooker version), Athlon C 1.2GHz, 
512MB PC2100 memory (ECC), 1GB swap partition, ReiserFS on all partitions
but 
swap and legacy FAT32.  I run a ksysguard kicker applet monitoring all sorts

of stuff, and user memory and buffers usually take about half my real memory

(256MB), with the rest cache.  Swap generally runs less than 200M (running 
130M now), and I seldom thrash unless I DO have a runaway program (like
KView 
during the KDE betas).  I've not seen that change w/ the new PAN.

I do know PAN takes forever (well, about a minute, I timed it) to load, and 
has pretty much since I started running it except during those betas when 
they had the fast start code that ended up creating race conditions.  I also

know that if I've just done something that cleared the memory fs cache, then

left a bunch of free memory, by the time PAN loads, I have filled memory
with 
file cache again, after it's read and parsed its message cache.  Actual user

memory use doesn't go up so much, but it does read in all those files and 
fill up memory with file cache.
