EventEmitter memory leak detected when running 'get'

[matiu]

After our client runs for a couple of hours, when calling

db.get(xxx, function(...

we get:

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
Trace

1. Any idea what could trigger this? This is a normal nodejs server, running with nodejs cluster (nr of instances = 4)
2. Since this exception happens async, and it is not catch and returned as 'err', it stops the execution. It should be catch and return as err.

thanks a lot.

PS: This is with multilevel running on the same box as the client, and the DB is on a local HDD.

Can you tell me which event emitters you added on db? Multilevel itself only registers .on('open', fn).

And you can catch those running db.on('error', function(err){ // your error handler })
