premixed combustion - parallel solver error

Craig

I am running a 2D premixed combustion case. When I run it in serial mode, a flame propagates from my spark down the length of my domain. When I run it in parallel mode, I get this error:

Updating solution at time levels N and N-1. done. iter time/iter

Primitive Error at Node 0: received Segmentation Violation

Error: Compute node encountered error

Error Object: #f

Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed.

Thanks,
