I had this problem several times, sometimes randomly. What helped me so far was using the following command at the beginning of the script before loading any other package!

options(java.parameters = c("-XX:+UseConcMarkSweepGC", "-Xmx8192m"))

The -XX:+UseConcMarkSweepGC loads an alternative garbage collector which seemed to make less problems than the standard GC.
