[petsc-users] Error with parallel solve

[Smith, Barry F.]

  Difficult to tell what is going on. 

  The message User provided function() line 0 in  unknown file  indicates the crash took place OUTSIDE of PETSc code and error message INTERNAL Error: recvd root arrowhead  is definitely not coming from PETSc. 

   Yes, debug with the debug version and also try valgrind.
