i tried to run SkaMPI benchmark on IBM-BladeCenterLS21-BCX system with 256 processors, but test has stopped on "AlltoAll-length" routine, with count=8192 for some reasons.

I have launched test with:
--mca btl_openib_eager_limit 1024

Same tests with 128 processor or less, have finished successful.

Different values of eager limit dont' solve the problem. Thanks in advance.
