This information is available in the mumps userguide
(http://graal.ens-lyon.fr/MUMPS/doc/userguide_4.10.0.pdf), Chapter 6.
Excerpt:
---
INFO(1) is 0 if the call to MUMPS was successful, negative if an error
occurred (see Section 7), or
positive if a warning is returned.

INFO(2) holds additional information about the error or the warning. If
INFO(1) = –1, INFO(2) is the
processor number (in communicator mumps par%COMM) on which the error was
detected.
---
So in your case there would seem to be an error on processor 359.

Best,
Klaus
