I am getting "caught segfault cause 'memory not mapped' " error when I use a big data with R in a linux server. The same function (svm, nnet or elasticnet) works when I reduce the dimension of the same data.

I get the following error when I use svm function (e1071 package):

*** caught segfault ***

address 0x7fdd271db2ec, cause 'memory not mapped'

Traceback:

I post also the session info:
