The reason for this is that dbx knows so much more about your program.
Basically, you are seeing the difference in the symbol table sizes
between sdb and dbx.  Dbx also has all the type information compiled
into the symbol table.  If you are running programs that are so big you
can only run one dbx at a time, I would look at the sizes of your swap
partitions and how much main memory you've got.  (You didn't say exactly
why you could only run one at a time, but I assume it must be one of
these.)  Usually, big symbol tables come from big programs, and big
programs have a tendency to eventually fill memory.
