Generally it means that a system routine (either an internal IDL one, or
a user added one) has aborted before it returned all its temporary
variables
back to the pool.

System routines can allocate temporary variables for internal use. These
temporaries should either be returned back to the pool before the
routine
returns, or passed back as the return value of a function. When control
passes back to the interpreter it cleans up any temporaries which are
still
in use and issues this message.

It's not really anything you should worry about, unless the system
routine 
which is not returning the temporaries is one you have written.

If you want to learn more about temporaries there is a section about
them
in the External Development Guide (look for "temporary variables" in the
index).
