Hi,

My screen has frozen. Is there a way to defibrillate it? 

  $ pstack 31472
  31472:  screen -S mutt -c /home/emallove/.screenrc-temp
  ff145f60 write    (5, 231a9a8, 9fcf)
  0006238c FinitTerm (8f3f0, 1, 18d40, 30af0, 30800, 0) + 32c
  00016438 Detach   (2, 2f31, 8f3f0, 2f313230, 80808080, 4) + 38
  000306c8 ReceiveMsg (89ee0, 0, 18d40, 30af0, 30800, 8f3f0) + 7e8
  000695b4 sched    (89704, 89000, 74400, f4240, 88800, 88800) + 334
  0001c0b4 main     (0, 8c000, 18c00, fffffff6, 18c00, 89ee0) + 2674
  00015d1c _start   (0, 0, 0, 0, 0, 0) + 5c

Based on the above stack trace, does anyone have an idea of
what is going on?

In this thread, someone advised to do "screen -x <session>",
and wait 15 minutes. I tried that, but screen -x has been
hanging for about an hour.

  $ screen -v
  Screen version 4.00.02 (FAU) 5-Dec-03
  $ uname -a
  SunOS ... 5.10 Generic_127111-07 sun4v sparc SUNW,Sun-Fire-T200

Thanks,
Ethan
