[R-sig-hpc] Error in socketConnection ... all connections are in use

[Joshua Ulrich]

You would have to rebuild R after increasing NCONNECTIONS in
src/main/connections.c.

It would be probably be easier to simply close connections you're no
longer using via stopCluster(), unless you really need >128
simultaneous connections.

Best,
