Is this normal?

[산도]

I am keep getting out of memory, this is a screenshot after I restarted my droplet (Im using digitalocean.com)
Is there anything that seems wrong?

@산도 500MB RAM are not a lot. Especially when using Redis.

Just to have it said.

How many posts/topics/users do you have? If you're getting frequent out of memory errors, consider setting up some swap on your droplet. There's a number of guides on how to do this with Digital Ocean.

@a_5mith still, the swap would be way slower than the normal RAM is, especially on DO's lame SSDs.

This would result in higher loading times and therefore in a higher bounce rate.

swap is used for old data that doesn't really need to be in RAM any more, I ran a forum with 24,000 posts on a 512mb droplet without issue. Added swap as a fallback, noticed no decrease in load times anywhere.

@a_5mith how big was your Redis DB?
(Just because of curiousity.)

@AOKP I get around 10 topics daily, Is 500mb ram still too low for it? Also does CPU matters?

[A Former User]

@산도 it is not really about the amount of the posts you get every day. Redis is an in-memory database, which means it runs the database out of your RAM. For small sites it is fine, for bigger ones it would mean that you need more RAM.

However, Redis does not seems to be your real problem here.

Whats your current NodeJS version?

@AOKP v0.10.25

@산도 well, actually it is quite normal. 80MB RAM are set for start up, if I am not mistaken and usually it goes around 120-160MB. Therefore these 25.2% mean 140MB RAM usage by NodeJS.

Which is fine, if you ask me.

What you could try though, is to use a different NodeJS version, e.g. 4, if you are only running NodeBB 0.9 and above.

Why is there so many loader processes there should be one. Are you running more than 1 nodebb.

[산도]

@baris This screenshot was taken right after turning power off/on of droplet, and I have it opened it with only one browser. But why do I see 14 of my name as processor, what's the problem?

[A Former User]

@산도 I also agree with @baris. What is your config.json? Do you use a script for auto start?

If yes, can you also share that one with us?

[산도]

@AOKP

This is screenshot after I stopping nodebb. I don't use autostart.

[julian]

@산도 How are you starting NodeBB?

[산도]

@julian I use ./nodebb start
