Thanks for the link. I'm looking into the issue, but it'll be a while before I can fix it. Aside from overflowing the short integer range for actor IDs, the client also runs out of memory while parsing the combat log. Fixing that with e.g. a -Xmx 4G results in another issue where the internal 48M output buffer is overflowed. I think we'll need to make some changes to the client's internals to reduce memory usage further. Will keep you updated.
