-- System Information:
Debian Release: 7.3
  APT prefers stable-updates
  APT policy: (500, 'stable-updates'), (500, 'stable')
Architecture: sparc (sparc64)

Kernel: Linux 3.2.0-4-sparc64
Locale: LANG=en_ZA.UTF-8, LC_CTYPE=en_ZA.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash

I receive the following error or trap from time to time on my server (a Sunblade 2000) which is running in "headless mode". When I try to start the 
GUI using startx the error occurs so frequently that I cannot use the console screen. My hardware seems to be functioning perfectly - I have not 
succeeded in starting the GUI (which I would like to do).

The error repeats for a while once it occurs and is shown below. If I type startx from the command line the error does not stop as readily and I have
 to reboot the machine to put it in a stable state.

I would really appreciate it if you could let me know if there is a work around for this problem?
