[Nek5000-users] Failing to converge when running in parallel

When running with mpi, I am currently experiencing an error with helmholtz which causes the solution to blow up quickly. The issue seems to disappear when running on lower mpi ranks. Is there a known issue which may cause this, or a work around I can employ? I haven't seen this before for similar mesh sizes. This case is a small mesh, but I plan on upscaling quite a bit. See attached for the run log and user file. Thanks, Jefferson Davis
