Java SOAP API - getMultipleLeads hangs even with small batch sizes

getMultiple leads is hanging for me even with a batch size of 1 or 50 vs 1000. It simply never returns.

I'm trying to get all leads so that I can deduplicate them all. I have logic to grab leads in batches of 1000 where I only return 2 fields for the best performance. This was working fine in May when I wrote it, but that's when I only had about 40k leads vs 500k now.

I'm setting up my request like this:
// Create Request
    ParamsGetMultipleLeads request = new ParamsGetMultipleLeads();
    // Request Using LastUpdateAtSelector
    LastUpdateAtSelector leadSelector = new LastUpdateAtSelector();
    GregorianCalendar since = new GregorianCalendar();
    since.set(2014, Calendar.MAY, 12);
    DatatypeFactory factory = null;
    try {
      factory = DatatypeFactory.newInstance();
    } catch (DatatypeConfigurationException e) {
      LOG.error("Could not create DatatypeFactory", e);

ArrayOfString attributes = new ArrayOfString();
It appears that the last updated at selector is what's causing an issue here, but it also looks like using that is the only way to fetch all leads. If I set the LastUpdateAtSelector to a few days ago everything works, but when I set it to something like May 2014 so I can get all my leads, it doesn't work.

Any ideas?

This sounds a bit like which was lacking a response.
