Red Hat Bugzilla – Bug 5812
Netscape still hangs on some java pages. Here's a trace.

As much as netscape has improved on Linux, it still doesn't get along with serious Java programs very well. As usaual, I'm working on a Sunday, and want to pay attention to my sports games. The NFL has this fantastic applet (http://espn.go.com/nfl/week/sco.html , NFL.com GameDay Live, linked to by javascript:launchGameDayWindow('buf').) Netscape runs this applet fine for a while, and then hangs. I've usually got a couple of windows open, and the Mail application as well. The GDB traces always show the same thing. I'm running on RH6.1, on a K6-2 300, with 64Megs of RAM, altough I've seen the problem on my PIII-450, 246Megs at work as well. Here are the RPMs: netscape-communicator-4.7-1.1 netscape-common-4.7-1.1 Here's the trace. It's always hanging in the same place, at least after a couple of traces. Since I don't have source handy, I haven't looked into it any more than this. It's interesting that it's hanging in X, however. Might be a bug in there worth hunting down. junkie% gdb /usr/lib/netscape/netscape-communicator GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.

Hmm... I haven't noticed this with the same applet. That's in the X threading code though. Presumbably a deadlock somewhere in Netscape.
I don't see it right now, either! I would guess that the only time that it really makes sense to run the applet is on a morning during all of the NFL games. The applet gets no updates of game statistics unless games are in progress. Maybe the rapid updates during a game triggers the bug? If you've got time (I realize this may not be an easy one to fix even if you can duplicate it), and a spare machine, maybe the bug can be duplicated by selecting the game update for a game scheduled for this weekend. I'd think you could set that up before the weekend, and check on it the following week. Thanks...
No, I'm saying I've run the applet during games, and not noticed the hang. I'll try again, but I don't know if I'll be able to reproduce it.
Then I guess I've got a problem. For what it's worth, I'm running on a K6-2 266, Intel 430TX chipset, 66MHz bus, 64M of RAM and a 16MB Diamond Viper V550 PCI video card. I'll try running again this weekend and see if I can duplicate it.
I am glad to see someone with the same problem I am having, since everyone else I talked to just told me to fix my font path! I am also running 4.7-1.1, but I am actually running RH 6.0 (because the installer wouldn't work for me). The trace is exactly the same, but I would like to add that I have experienced problems with just about every Java site that I visit, but it doesn't always happen. This one seems to give me crashes more frequently: http://station.nasa.gov/ There is a little scroller on the right, if it works. A "workaround" for me is to just disable Java support, but that's not much of a solution. I have also observed that it happens more frequently when I click on a link to a Java page, and while waiting, move the mouse to another window so that the Netscape window loses focus (but I have never collected statistics). This may or may not have anything to do with the problem.
I tried out your link to http://station.nasa.gov/, and got a lockup after leaving it running for a while. I've noticed that netscape tends to crash hard when the fontpath is bad, on a variety of java pages. I think I have my fontpath correctly doctored (attached below). The only other thing that I can think of that may not be stock on my X setup is that I changed /etc/X11/fs/config to default to 100dpi a long time ago, when the default was 75. Here's the line I'm using (I have no idea what the default is today - I guess I should check into that). # 100 x 100 and 75 x 75 default-resolutions = 100,100,75,75 Here's my font path: /usr/sbin/chkfontpath Current directories in font path: 1: /usr/X11R6/lib/X11/fonts/misc:unscaled 2: /usr/X11R6/lib/X11/fonts/100dpi:unscaled 3: /usr/X11R6/lib/X11/fonts/75dpi:unscaled 4: /usr/X11R6/lib/X11/fonts/misc 5: /usr/X11R6/lib/X11/fonts/Type1 6: /usr/X11R6/lib/X11/fonts/Speedo 7: /usr/X11R6/lib/X11/fonts/100dpi 8: /usr/share/fonts/default/Type1 9: /usr/X11R6/lib/X11/fonts/75dpi
I tried the NFL link again this weekend and got the same problem. It took a while for the problem to occur, after I browsed through a couple of games, and then did some browsing elsewhere while the NFL window ran in the background. YMMV.
I actually was able to reproduce this this weekend. I'll forward it on to netscape; not sure if there's anything we can do about it, though. :(
Thanks. My guess is the solution is to wait for Mozilla to enter beta :)
Ever since I upgraded to Redhat's new gnome files, the Netscape crashes have become worse. It used to be limited to a handful of sites, now it happens all of the time and is getting very irritating. I can find no pattern to it either, sometimes it will lock up even though I just have it up and am working with something else.

Is there any chance that this can be fixed any time soon?
