Hi,

I downloaded the nightly trunk snapshot openmpi-1.7a1r23032. I recompiled openmpi and my test code, and put back the btl_tcp_eager_limit to default.
The bug seems to be fixed. I don't have the segfault anymore even with big array (up to 685MB). 
Thanks to all the developpers.

There is a ticket on the bug trac about this problem that may need to be updated :
https://svn.open-mpi.org/trac/ompi/ticket/2336

Regards,

   TMHieu

Hello,
You can get nightly trunk snapshot from here
http://www.open-mpi.org/nightly/trunk/
You can grab openmpi-1.7a1r23032 and test it. This will be great.
