I am struggling with the following problem:
  ERROR: LOCAL:EXIT:SIGNAL: fatal error
  ERROR: Fatal signal 11 (SIGSEGV) raised.
  ERROR: Signal was encountered at:
  ERROR: MPIU_Handle_obj_alloc_unsafe (/tmp/7b663e0dc22b2304e487307e376dc132.xtmpdir.nnlmpicl211.16412_32e/mpi4.32e.nnlmpibld05.20130522/dev/src/util/mem/x86_64/debug_dynamic/../../handlemem.c:353)

  WARNING: starting premature shutdown
I got this diagnostic message by using the Intel ITAC. In our application we do a lot of 1sided passive "put" and "get" operations across working MPI processes. The memory attached to MPI's windows is allocated via 'malloc'. The program is running on the HP SL230s compute server equipped with two Intel E5-2660 (2.2 GHz Sandybridge) processors with 8 cores each (i.e. 16 cores per compute server). The problem starts only when I start using more than 4 cores on a single node, regardless 'I_MPI_FABRICS' (=shm,dssm) setting and compiler's optimization leve used. The software stack is listed below:
I am wondering if there is a quick solution to this problem?
Thank you in advance!
