I apologize for asking again, but I don't know where else to
turn and I appreciate all of your advice after yesterday's crash
(special thanks go to Dr. Tom Blinn and Whitney Latta for their
exhaustive explanations today).
Even with the wonderful help, I have been unable to diagnose the
cause of the crash, but the slow-downs are happening again.
Intermittantly, the system seems to buffer all keystrokes. I usually
have several windows open, today one as root and several as a normal
user. When the slow-down occurs, it is in ALL windows -- even root's.
The reason I say the system is buffering the keystrokes is that I
can keep typing even though the keystrokes aren't showing up in the
window, and after a bit (up to 30 seconds or more), they all show up.
Any ideas on what I should check?
Here are some things I have looked at:
