 Known Problems
 ==============
+* The PathScale MPI implementation, accessing a Panasas file system, would
+  cause H5Fcreate() with H5F_ACC_EXCL to fail even when the file is not
+  existing. This is due to the MPI_File_open() call failing if the amode has
+  the MPI_MODE_EXCL bit set. (See bug 1468 for details.) AKC - 2009/8/11
+ 
 * Parallel tests failed with 16 processes with data inconsistency at testphdf5
   / dataset_readAll. Parallel tests also failed with 32 and 64 processes with
   collective abort of all ranks at t_posix_compliant / allwrite_allread_blocks
