Dear MPICH discussion group

I am trying to run a MPI program, but I fail with the following error:

1: Fatal error in MPI_Recv: Other MPI error, error stack:
1: MPI_Recv(186)................: MPI_Recv(buf=0xbfdf70e8, count=52,
MPI_DOUBLE, src=0, tag=0, MPI_COMM_WORLD, status=0xbfdf6f34) failed
1: MPIDI_CH3i_Progress_wait(207): sock_wait failed
1: MPIDU_Sock_wait(202).........: unexpected operating system error
(errno=22:(strerror() not found))
rank 0 in job 71  lidic01.unsl.edu.ar_39689   caused collective abort of all
  exit status of rank 0: killed by signal 11

The program ejecute very well with smaller input size, but when I row the
size it crashing.

Let me know if this error sounds familiar to you and if you have any
suggestions for what to do here.
