Subject:    [gentoo-user] mozilla 1.2.1 works for a while, then creates lots of pipes and dies

This is a strange one as well, I had it happen the last time I upgraded
to 1.2.1, but I rebuild all of gnome (to get 2.0.3) and upgraded to
1.2.1 and galeon 1.2.7 at the same time, and thought my problems were
gone.

Basically it goes something like this.  I compile mozilla and galeon
(unstable) and it all works dandy, I can quit and restart both apps
fine.  At some point mozilla stops working properly, and segfaults on 
startup.   It will sit there for a while, using 100% cpu (my
system-monitor is pegged, but the system is still responsive) for a
loooong time, until it crashes with a segfault.

Using strace and lsof it looks like mozilla is spawning off pipes like
there is no tomorrow, until it can't do it anymore and segfaults.  While
it is sitting there spinning an "lsof -n | grep mozilla" shows something
like the following:

mozilla-b 2992    alan   30r  FIFO        0,6              93002 pipe

The list of pipes will grow and grow until it is quite long, then boom,
mozilla dies. 

If I unmerge then remerge, it will work ok for a bit, but I obviously
don't want to do this too often!  The precompiled tarball from mozilla.org
doesn't do this of course, and I can't find mention of anything like
this anywhere in the forums.  I've tried with and without xfs running,
and have deleted the font-cache files in my /usr/lib/X11/fonts/*
directories.  I'm wondering if this has something to do with the xft
engine somehow.  

I know when moz starts up it does a bunch of checking for fonts and they
go scrolling by on the console window.  Anyone know what file/directory
this info is stored in?  Maybe I can nuke it and see if that is the
problem?

Anyway, if anyone has any ideas, I thank you in advance.  I'd rather not
go back to 1.0.x, but if I have to, I will.
