When I run my code with the -log_summary option, it hangs indefinitely after displaying:<br>

========================================================================================================================<br>
Average time to get PetscTime(): 9.53674e-08<br>
Average time for MPI_Barrier(): 0.00164938<br>
<br>
Is this a common problem, and if so, how do I fix it? This does not happen when I run the example programs - only my own code, so I must be at fault but without an error message I am not sure where to start. I am using petsc-3.1-p7. Thanks for your help.<br>
