Thanks, Sam! trying with increased -Xmx..
Interestingly enough, project_build goes on to load the next data source and data is getting into the database for the source on which this error occurs. It happens on one of the longest data source.

Sometimes it recovers with just the WARNs, and sometimes it'll drop the connection with a socket timeout as you see. You'll want to boost your resources, likely on the database server, but perhaps also on the machine running the IM code.
