reading fasta file out of memory error

Hi,

I have an 1.8 GB fasta file and I was trying to read it with the following
code as in suggested examples page.

LinkedHashMap<String, DNASequence> seqs =
FastaReaderHelper.readFastaDNASequence(new File(args[0]));

I don't get any error for small size files but it gives the following error
for big files.

Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit

Is there any efficient way?

Thanks in advance.
