I have 3 different mongodb servers (v3.0) running in a replica set on a vlan, and 2 separate web servers running php/nginx on another vlan (php-mongo 1.6.5). 

If I just STOP the mongod process, all goes fine. If I kill one of the mongo servers (turn it off or unplug NIC) the replica set does a good job at picking a new master, but my PHP (v5.4.35) scripts seem to hang and that eventually just kills the web servers.

Test script:
function write($filepath, $metadata, $database, $collection)
   $mongo = new MongoClient("mongodb://stgndb01:27017,stgndb02:27017", array("replicaSet" => "stgndb00"));
   $db = $mongo->selectDB($database);
   $gridFS = new MongoGridFS($db, $collection);
   $result = $gridFS->storeFile($filepath, $metadata, array("w" => 0));
   if($result === FALSE) {
      echo 'KO';
   } else {
      echo 'OK';

Thanks for reporting this issue. Development for the "mongo" extension is primarily managed through our JIRA project, so I've opened to track this issue.
