Mirror crashes daily and pm2 doesn't get it up again

[looolz]

Hi!

My mirror crashes every day. It just goes black and works again if I manually quit it (pm2 will then restart it).

I checked the logs by doing

pm2 logs mm

Which gives me:

Any ideas on how I could fix this?

[looolz]

I just did a

git pull && npm install

To see if it makes a difference.

log says:

So first thing to verify: what is the module who do this
so isolate (disable module one by one for verify)

when you found the module trouble:
try a git pull on it
If not works gain … report issue to developer

@bugsounet Thank you! If it crashes again, I’ll start by disabling 1/2 of the modules until I find the problem. This could take days, hope I don’t have to 😐
