p4_error: net_recv read:

[Gerard Gorman]

Hi,

I'm having this problem on our cluster while using MPICH1.2 (alphas
running osf1 connected via a switch):

rm_l_5_3390:  p4_error: net_recv read:  probable EOF on socket: 1

I have been searching the archives/net for an insight to the problem but
all I have found is people reporting the same problem (under linux). 

The problem arises only when I run on some number of processors greater
than 4. The processes are all *reading* the same file which had been NFS
mounted across the nodes (I have included the usual perror checks). 

Has anyone experienced similar problems/know what I should be trying to
fix?

All help appreciated,
g
