segmentation faults

I have a openmosix cluster of 5 nodes running the 2.4.26 kernel and
Redhat AS 3.  We recently upgraded from an older version of RH and
openmosix to this version.  Until the upgrade, things were running
smooth, but now binaries compiled using a fortran (Lahey Fortran)
compiler first lock up the machine they are run on, then throw a
segmentation fault and core dump after a while.  When I disable the
openmosix service, the binaries run fine.  It doesn't seem to be
specific to the fortran compiled programs though, since another program
we also use, R, does the same thing.

 

Any thoughts on how to begin to troubleshoot this?

 

Thanks,
