title: Failed R instances + RODBC
body: <p>Quick question: I am running multiple R instances parallel in batch mode using an RODBC connection, and randomly one (or more) of my instances is failing. If I go back and run the instances one by one, all of them are successful. There is no error in the log, and I am just trying to deduce where exactly the issue is coming from. My main hypotheses are that I am hitting a memory heap top and the instance is failing, or (more probably) there is some kind of time out happening with the RODCB connection. Any suggestions?</p>
  
  <p>Thanks,</p>
