Description markster 1999-07-17 14:08:05 UTC
Netscape contains very serious memory leaks.  If left
unattended on a page with autorefresh (like our incoming
queue page at Linux-Support.net), it will consume memory and
swap until nothing is left.  On my system, leaving netscape
open for four hours on a page that refreshes every 60
seconds, fills out the remainder of my 128MB of RAM and
128MB of swap, causing a panic (although nothing is logged,
and being in X-windows, I'm unable to see anything).
Userspace simply dies, while ping's and other kernel-only
functions remain intact.

I have a test technician account that I can make available
for anyone who wishes to duplicate the bug.

One potential work around I am currently testing is to add
"ulimit -d 32000" to /usr/bin/netscape to keep its
consumption under control.

What version of Netscape are you using.  I have seen a considerable
improvement in the leakage problem with release 4.61-1.

Comment 2 markster 1999-07-19 15:06:59 UTC
netscape-communicator-4.6-1

As provided in the updates to RedHat 6.0...

you might also try upgrading glibc to the latest version in Raw Hide;
there were memory leaks in some of the host resolution code; a
process that auto-refreshed would certainly run into this.
