[R] increasing the # of socket connections

Dear "R-help"ers,

using snow on socket connections, I ran into the following error

> cl <- makeSOCKcluster(hosts)

	Error in socketConnection(port = port, server = TRUE, 
	blocking = TRUE : all connections are in use

with "showConnections(all=T)" showing 50 open connections.

As - for administrative reasons - I would prefer to use snow's SOCK capabilities (instead of MPI and the like), I wonder if there is a way to increase the number of simultaneous open connections allowed in an R session (~100 would be sufficient).

Any help/hints are greatly appreciated,
best regards,
