1. Please cite the former part of the thread.
2. We need a reproducible example that shows the "standstill" situation.
3. I doubt you can provide 2: it probably just looks like "standstill",
but is the slow memory access for virtual memory. Therefore:
a) upgrade your R (13.2 is an invalid version anyway, 2.14.1 is the
recent release version)
b) Try on a bigger machine or upgrade the available memory in your
machine. Try on a 16Gb machine, for example. This is easily possible
with simple modern home computers nowadays, 4*4 Gb is roughly 100 EUR
nowadays.

Dear all,
I know this may have been already discussed, but I could not find a
solution.
I am using R 13.2 64 bit on a 64 bit machine dual core. I'm fitting a Cox
proportional model to a matrix 1e06x7. Before starting the model fitting I
set memory.size(max=10000) and I do a clean of the garbage collector (gc()).
Once launched, the program works, works, works and then, after a certain
period, it reaches a standstill, with CPU usage 50% and memory usage
somewhere above 5GB, flat! Maybe when swapping to the virtual memory the
process gets stuck. Any idea on how to solve this issue?
Best, Marco
