I used to see this with fvwm1 when I would set the system clock backwards.
It would only be effective until the clock wound back to where it started.
I found this while playing with a time-setting process learning how to
keep my Linux box sync'd with certain other computers. It had slipped a
significant number of minutes ahead of the real world. I probably
wouldn't have noticed only a second or two of delay. The first time I hit
it, I restarted. If you are setting the clock back to Oct 8 while fvwm1
is running, you might get the same effect but lasting for a month. I
guess it is possible on other OS's such as Solaris, that the freeze might
never time out.
All this is prelude to asking you whether the freeze-ups are somehow
correlated to NTP or other time-synchronizing procedures you might have
active on all of your machines? One of my colleagues here has observed
what he feels is unsatisfactorily smooth clock manipulations from xntpd on
his Linux setup. Winding the clock backwards might be your trigger event.
Hope this helps....
