Bus Error

[Lynn Lively]

Does anyone know what a "Bus Error" is? I've got a very complicated program  
running that monitors and schedules the activities of about 10 son processes.   

It uses alot of dynamic memory, an IPC message queue, I'm also catching some  
signals (SIGALRM, SIGCLD). The program dies in various spots, so I'm obviously  
 
dealing with a dynamic condition of sorts, but don't have a clear idea where  
to look in the program for the problem. Any help would be appreciated.
