title: MongoDriver.sndrcv(query): comms error (Can't reconnect)
body: <p>I have a strange error suddenly when running my Opa script after it successfully compiled:</p>
  
  <pre><code>Jeroens-MacBook-Pro:CollabTextEditor jeroen$ ./CollabTextEditor.exe 
  Http serving on http://Jeroens-MacBook-Pro.local:8080
  DbGen/Mongo Looking for MongoDB in directory '/Users/jeroen/.opa/mongo'
  DbGen/Mongo MongoDB seems launched (pid:438)
  MongoDriver.sndrcv(query): comms error (Can't reconnect)
  File "lib/stdlib/apis/mongo/log.opa", line 73, characters 5-16, (73:5-73:16 | 2930-2941)
  fail: -1
  </code></pre>
  
  <p>A quick Google search didn't give me any answer :s So I tried to find the file log.opa which is mentioned in the errormessage but <code>sudo find / -name "log.opa"</code> returned nothing. Any help?</p>
