At first, I'd try with an R version from 2010 rather than one from 2007.
Next, I'd try to be sure to really have a 64-bit version of R rather
than a 32 bit one which is what I suspect.
Best,

I am using R 2.6.2 - x86_64 on a Linux x86_64 Redhat cluster system. When I
log in, based on the specs I provide [qsub -I -X -l arch=x86_64] I am
randomly assigned to a x86_64 node.
I am using package GenABEL. My data (~ 650,000 SNPs, 3,000 people) loads in
okay and I am able to look at the data using basic commands [nids, nsnps,
names(phdata)]
The problem occurs when I try to run the extended analysis: xs<-
mlreg(GASurv(age,dm2)~sex,dta)
