From this output all I can tell is that it occurs all of a sudden right before calculating k and omega.. Usually around the same timestep. However, if I start from the last saved state, the FPE will usually take longer to appear.. Anyone has any hints for me?

PS: I will provide the full logfile if anyone is interested.
