[R] write.csv causes system() and ? to stop working

I have a large (100MB, 940k lines) csv file. If I run
g <- read.csv('combineTfe-dataFrame-TD.dat')
write.csv(g, file="tmp.data");
Now ?mean returns without printing anything to screen and
system("touch test.dat") does nothing.
If instead I just write out the top of the data, as in
g <- read.csv('combineTfe-dataFrame-TD.dat')
tmp = g[1:100,]
write.csv(tmp, file="tmp.data");
?mean and system("ls") have the expected beviour.
This is on an AMD64 machine running Ubuntu, under both R 2.6.2 and
2.7.1 (a fresh install). The same minimal code works fine on a
different (x86) machine.
Any help will be greatly appreciated.
thanks,
Scott
