Hi,
We are using openmpi 1.4.1 on our cluster computer (in conjunction with Torque). One of our users has a problem with his jobs generating a segmentation fault on one of the slaves, this is the backtrace:
[cstone-00613:28461] *** Process received signal ***

The other slaves crash with:
[cstone-00612][[21785,1],35][btl_tcp_frag.c:216:mca_btl_tcp_frag_recv] mca_btl_tcp_frag_recv: readv failed: Connection reset by peer (104)
Since this problem seems to be happening in the network part of MPI my guess is that there is, or something wrong with the network, or a bug in OpenMPI.
This same problem also appeared at the time that we were using openmpi 1.3
How could this problem be solved ?
(for more info about the system see attachments)
Thx,
Werner Van Geit
