I'm about ready to use a big profanity because I had a really nice
message worked up to reply but then netscape mail used up all my memory
and quit blowing away about 25 min of typing a message. Anyway attached
are the results from ps and free at about 5 min before it wiped out all
my communicator apps I had open (dumping all the text I had typed
!!!!). Someone asked if I had used the debian package to install it,
yes I did. Maybe this problem could be attributed to my kernel? Maybe
it doesn't do memory management correctly? I also noticed that right
after I went to a page which used java and the java vm started that my
memory (now swap) usage went up by 5 meg! Is there someone else that
may know more about this? It is starting to get really annoying when I
have to have a xterm open all the time and every 5 min check the amount
of free space to see if I have to close netscape and open it again to
stop this memory growth problem. Is there anything that you know of
that I can try (there's seems to be some weird bug here). Maybe when
netscape gets compiled for libc6 I won't have to load the old v5 libs
and it'll save memory???
