This is error:
TypeError: Cannot use 'in' operator to search for 'issued' in undefined
at Manager.garbageCollection (/usr/local/src/livechat/node_modules/socket.io/lib/manager.js:1023:21)
at wrapper as _onTimeout
at Timer.listOnTimeout as ontimeout

It dont know when it raise. while using app, the app die, I check log and saw it.
my socket.io version: 0.9.16, mongodb 1.4.7, Iam using cluster and domain in nodejs

this looks like an error with socket.io

I dont think so, you can refer some links below:
socketio/socket.io#408

that still doesn't show that the error is caused by this module. and you might not get much help from socket.io devs either since you're using an older version.
