You can also use our (Mission Critical Linux's) crash command, assuming
you're on a supported platform (i386, alpha and ppc). For example,
to get a stack trace of netscape:
crash> ps | grep netscape
835 673 1 c4298000 IN 13.7 29792 17896 netscape-commun
837 835 0 c2ff8000 IN 0.2 16840 324 netscape-commun
crash> bt 835
PID: 835 TASK: c4298000 CPU: 1 COMMAND: "netscape-commun"
