pm2 has too many open files?

[mattcasey]

My app was restarting every 10 minutes or so for the past 12 hours with no error and very low CPU/memory usage, then I recently got this error from winston:

Error: EMFILE, too many open files

however running lsof showed that the culprit was pm2. I could see the following repeated a hundred times? or so. I'm just looking to see if you can help determine in what situation pm2 would not close the file so that I can avoid it in the future!

node      29520      ubuntu  965w      REG              202,1  2791568   413813 /home/ubuntu/.pm2/logs/receiver-err-0.log
node      29520      ubuntu  966w      REG              202,1 20320184   413812 /home/ubuntu/.pm2/logs/receiver-out-0.log
node      29520      ubuntu  967w      REG              202,1  2791568   413813 /home/ubuntu/.pm2/logs/receiver-err-0.log
... 

We do a lot of pm2 restarts 'app name'. The pid 29520 is not pm2 itself, but the process of my script that is maintained by pm2. Doing 'pm2 kill' cleared out the open files. node: v0.10.29, pm2: 0.9.1

This is fixed with the latest pm2 version
