Edit the sstablesplit script directly and modify this section:

if [ "x$MAX_HEAP_SIZE" = "x" ]; then
    MAX_HEAP_SIZE="256M"
fi

Set the maximum heap to a higher value. For example, set it to 1GB:

    MAX_HEAP_SIZE="1G"

If you have large partitions in the SSTable, it might be necessary to bump it up further to 2GB. Cheers!
