Hi,
I am experiencing a very strange problem. I am importing some big xml-files
and store them into mongoDB. The algorythm is a typical async loop:
doLoop = function( it, callback_loop ) {
if( it < no_of_items ) {
storeToMongo( ..., function( err, result ) {
...
doLoop( it+1, callback_loop );
});
} else {
callback_loop();
}
};
doLoop( 0, function() {
...
});
Now (suddenly without any remarkable change in the code) I get the
following error while performing the loop:
events.js:72
throw er; // Unhandled 'error' event
^
Error: connect EADDRNOTAVAIL
at errnoException (net.js:901:11)
at connect (net.js:764:19)
at net.js:842:9
at dns.js:72:18
at process._tickCallback (node.js:415:13)
The error happens after approximately a minute. The number of items
processed in the meantime is quite the same, but not exactly.
I tried to find out what connect/net causes the error, but I am lost. There
is not socket-connection in my code. I have a connection to redis, but that
is o.k. Is it the mongoDB-connection? But why does it get lost suddenly?
The only thing that helps to run through the whole loop is to perform the
recursive loop call within the mongo-callback like this:
setTimeout( function() {
doLoop( it+1, callback_loop );
},1);
Anyone out there who has an idea what is going wrong here?
Thanks,
Jochen
