[MPICH] Error while running an MPI program using MPICH

[Prakash Velayutham]

Hi,

I am using MPICH 1.2.7 under SuSE Pro 9.3 (kernel - 2.6.11.4-21.9). When 
I run an MPI program, after about 4 hours (not consistent though), I get 
this error. Does anyone know how to resolve this?

p0_4476:  p4_error: interrupt SIGx: 15

I used to get errors about ipcs earlier ( a year back or so), but I 
clean up using cleanipcs.

Thanks,
Prakash
