RPG Compile - Weird Error

[SCarter@xxxxxxxxxxx]

We have a couple of programs we are trying to compile that are causing
weird errors.
Here is the scenario. we submit a source to compile the compile listing
gets pretty much to the bottom, the CPU percentage jumps up for this one
Job into the 90
we ultimately try to end the job but it will not end.

1.  The error happens in either a batch or interactive compile.
2.  The compile never finishes.
3.  This just started on Friday and no one here admits to changing the
system in any way.
