What is the cause of ORA-03100?

I'm running ORACLE 7.0.12.2.0 on A/UX 3.0. I occasionally ran into ORA-03100 error while doing a "EXEC SQL FETCH..." The error description is as follows:

  ORA-03100: communication area cannot be allocated; insufficient memory

I'm pretty sure that I have plenty of memory free. The ORACLE Error Messages manual suggest that I contact ORACLE. I have done that in the past, but I was transferred back and forth between their different support departments and eventually did not get any answer (sigh).

Can anyone point out some possible causes of this error?
