Dbx frequently gives I/O errors while reading either the symbols or when 
doing the initial processing of a core.  We found it necessary to make sure
that the workstation server had allocated swap space for the workstation 
running dbs which was at least four times the size of either the core of the
executable.  In my case, I was working with an 8 MB executable that had made
a 9 MB core image, so a 40 MB swap space was insufficient but 50 MB was.  It
had to read in 103,000 symbols (C++ generates *LOTS* of symbols) but dbx was
able to trace the program after taking about 20 minutes to get set up!!!
