Graphics error

[Stefan Farestam]

   A graphics program of mine occasionally makes the window server
   go down. Although exhaustive searches for bugs, I have not been
   able to locate the cause. The program runs on a 4D25GT under
   system release 3.2.1. The following are some excerpts from
   /usr/adm/SYSLOG taken right after the crashes:

   I wonder if someone might have a clue as to how to interpret
   these error messages, and consequently being able to hint me
   what to look for in my program.

   Any suggestions appreciated.

   Thanks,
          Stefan Farestam
