You should be able to set limits on memory use for a process in the operating
system, eg with limits or ulimits under Unix-alike shells.

My group is working with datasets between 100 Mb and 1 GB in size, using
multiple log ins. From the documentation, it appears that vsize is limited
to 2^30-1, which tends to prove too restrictive for our use. When we drop
that restriction (set vsize = NA) we end up hanging the server, which
requires a restart. Is there any way to increase the memory limits on R
while keeping our jobs from hanging? Having to restart the server is a
major inconvenience, second only to memory limitations in R.
