Try doing $HistoryLength=0; at the start of a session when
working with large data sets. This will keep Mathematica from
keeping copies on the In/Out stack which can quickly consume memory

Another approach might be to load the package CleanSlate before
importing large data sets. CleanSlate can restore things to the
state they were in immediately after the package was loaded
including clearing the In/Out stack.
