PM2 Daemon Dying in Prod

[bartspedden]

Here's some environment information to start with

OS: Linux d6proddisp4 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
PM2: 0.12.1
NodeJS: v0.11.14

We are using the the generated init scripts to start/stop pm2.

We have 2 application running - each with 4 workers.

Over the past 3 weeks we have the PM2 God Daemon die 3 times with the following message showing up in the pm2.log

Error: channel closed
    at ChildProcess.target.send (child_process.js:413:26)
    at sendHelper (cluster.js:657:8)
    at RoundRobinHandle.handoff (cluster.js:198:3)
    at RoundRobinHandle.distribute (cluster.js:184:20)

Any ideas what might be causing this?

nodejs/node-v0.x-archive#8792 as we wait for this bug fix, we will make a hotfix (not very clean) on the PM2 side.

If you want to avoid this use the fork mode instead (or multiple process forked on different ports then nginx balancing requests between these processes)
