Building of the system failed with communications error

When building a design for the RT685EVK I am receiving an error 'Building of the system failed: failed, communications error'.

Building other designs works fine.  If I try to just 'run' the design I get the same error.

What is the best way to determine and correct the issue?

More info.  I discovered the messages tab which has this final missive.  Any suggestions?  Is this a bug in the library when FIR filters are used?

I was able to track this down to the IPC buffer being too small.  After increasing the size the designs now load.  Unfortunately the BSP had numerous hard coded values to track down instead of a single #define.  To make matters worse, the same size was not used in all places.
