Pm2: Getting "Maximum call stack size exceeded" during "pm2 stop ID"

[estliberitas]

Hi guys!

I have a rather big Node.js application. And I run it in a cluster mode. Also I have set up graceful reload according to documentation. And it worked perfectly while I was deploying from day to day.

Today, I had to apply hot fix, so I did not care about graceful reload. Uptime was about 30 days. I hit pm2 restart all and in process list I had status errored for first process. And error message was kind of "Process 1234 not found". Then I tried pm2 stop 0 to stop first process, and still was getting errored state. I hit last command some times and finally got it state stopped for first process. Then, I manually did the same for other processes.

And then, I got error report with this error from my application. The thing error reporting is set in application (uncaughtException listener), so it may mean error comes from PM2 code which is executing worker process if I'm correct. By the way, I can't say after what command this exception was fired.

RangeError: Maximum call stack size exceeded

I created a gist with all the important logs.

PM2 version: 0.15.5
Node.js version: 4.1.2
OS: CentOS 6.5

Fixed in development branch

If you want to try it:

$ npm install Unitech/pm2#development -g

If it is not important to have a single common location to have pm2 metadata folder stored on a installation. then you may try the following:

go to your node project where pm2 will be used.

for Windows
set PM2_HOME=.pm2

for Linux
export PM2_HOME=.pm2

this will place the .pm2 folder inside your project where pm2 will have write access.

Thanks nklt ! Your solution has fixed my "RangeError: Maximum call stack size exceeded" issue
I think that Windows was not able to access to my pm2 metadata folder.

If it is not important to have a single common location to have pm2 metadata folder stored on a installation. then you may try the following:

just run it in the cmd (windows - with admin permissions)
