php Mongo DB MongoConnectionException' with message 'the connection has been terminated, and this cursor is dead

I am trying to get all records from a collection which has 5000 recs and loop through each record and do some operation and move it to another collection.

However after processing about 1100 recs , I get the following error

'MongoConnectionException' with message 'the connection has been terminated, and this cursor is dead'

How can I resolve ?


Mongo cursor timeout could be the reason. Set MongoCursor::$timeout=-1 for keeping cursor alive

It looks like this:

$mongoConn = new \MongoClient('mongodb://ip:port', ['socketTimeoutMS' => 120000]);
$collection = $mongoConn->selectCollection('database_name', 'collection_name');
$cursor = $collection->find();
while ($cursor->hasNext()) {
    $record = $cursor->getNext();

But you still can get an error "Maximum execution time of 30 seconds exceeded". This can be solved too:

ini_set("max_execution_time", '60');


set_time_limit (60);

or write in .htaccess:

php_value max_execution_time 60

But it's bad decisions. Sooner or later, the script does not run out of time to complete and you will get the same error. I would recommend you use indexes:
