[olug] browsers

[Nick Walter]

Have you run an strace to find out what Mozilla is trying to do when it
locks up?  I find that's a great way to find out if an application is
locking up on a system call.

If you've never run an strace, here's a quickie howto

1.)  Find the PID of the process you want to trace.  You can use 'ps
-efw' as root to see the names, PIDS, and a bunch of other stuff about
all running processes.  In regards to mozilla, the process name you are
looking for is mozilla-bin.

2.)  Once you know the PID, do an 'strace -p <pid>' where <pid> is the
PID of the program you want to strace.

3.)  If the strace just keeps scrolling nonstop, the process isn't
frozen, though it might be in an infinite loop or some other state that
keeps the process from behaving properly.  If the strace stops at some
point and doesn't continue, then note down the last few lines.  The last
line in specific is the system call the program is frozen on.  Usually
the name of the call or the name of a device being referenced will give
a good general idea of what the process is trying to do that freezes
it.  From that point more specific and focused troubleshooting is
possible.
