[Nek5000-users] Nek: abnormal termination by signal 11

Hi all,
I have recently encountered the following error during the first time step when running on an IBM/BlueGene Cluster:
...	  
1  Hmholtz VELZ       5   6.4574E-08   1.0000E-04   1.0000E-08   1.0000E+03   F
          1  Hmholtz VELZ       6   2.6260E-09   1.0000E-04   1.0000E-08   1.0000E+03   F
          1  Hmholtz VELZ       5   2.6260E-09   1.9523E-01   1.0000E-08

This has happened for different user files, different parameters and resolutions, so I am not sure where to start looking. Has anyone else seen this problem? Is this likely a Nek or an IBM related problem?
Best wishes,
Jan
