Phase Unwrapping Error (Abnormal Exit)

I am facing this error during phase unwrapping. can someone tell me what is “abnormal Exit” means, and what should I do now?

Regards

There are many possibilities, including: corrupt input data, hitting a resource constraint (disk full, out of memory), hardware faults, or program logic errors.

Is the error reproducible? Do you have adequate free space on your mass storage? Use Windows Task Manage to monitor memory usage while the program is running.
