[nos-bbs] Jnos crash randomly

Hi Jean,

Seems to be over-writing past the end of a buffer or something like that.
Run it with the gdb debugger and mail the output to Maiko see below.
gdb is available as a deb package. ('aptitude search gdb'  from the shell)

This is from Maiko's site;

Using GDB is easy. With JNOS running already, find out it's pid, using
   the linux command, 'ps -ef | grep jnos'. Once you know what the pid is,
   then run the gdb debugger something like this :

    gdb -p pid

   GDB will load, JNOS will hang temporarily, and GDB will suddenly give
   you a prompt. Enter the command, 'continue', at the prompt, and JNOS
   will continue to run again.

   When a crash occurs, GDB will break out to the prompt again, and JNOS
   will hang. Take a screen shot of what GDB printed out, then type in
   the command, 'back full', at the GDB prompt, and note the info that
   appears. Please send all of that information to me, with a brief
   explanation of what might have been going on at the time.


73,

Bob VE3TOK
