As we all know Netscape tends to crash or freeze very often. Crashes are characterized by Netscape window disappearing from your desktop and freezes by Netscape stopping responding to the mouse and keys and by not redrawing it's window.
If you solve this situation by killing Netscape window or just by exiting the X session Netscape will still be running in the background and consuming all the CPU time that it can. The computer will run every other process slower.
ps uax | grep netscapeThis will give you something like:
rsousa 9415 0.5 26.6 45060 33720 ? S 02:46 4:11 /usr/lib/netscape rsousa 9427 0.0 0.0 0 0 ? Z 02:46 0:00 [netscape-commun rsousa 12450 0.0 0.3 1240 500 pts/0 S 16:38 0:00 grep netscapeuse the command kill to get rid of the rogue process:
kill -9 9427Where 9427 is the PID (process id number) and will be different every time. If the desktop stopped responding to the mouse you can either switch to another VT (virtual terminal), login and kill netscape or login remotely from another machine. To switch to a VT from a X session you use:
Ctrl + Alt + FnTo switch back to the graphical console (or between consoles) you use:
Alt + F7The number n chooses the VT you want (usually 1 to 6). Don't forget to exit your login session in the VT.
It is important that you kill your own processes since no one else can (except for root). Also it makes the computers much more pleasant to work with.Though these instructions focus on netscape they can be applied to any other program that crashes and stays running in the background.
