Ever since I tried out the AI plugins (and later removed them again), my machine totally hangs during /admin/upgrade. Not every time but approximately 80% of the time. Usually my whole EC2 instance freezes and I have to do a hard reboot through the AWS EC2 web UI. Today it hangs again. To my surp…

[image] Uwe Keim: the AI plugins The official ai plugin? I would run this from the console and see where it gets stuck, share the logs.

Yes, the official plugin. I uninstalled it by removing the plugins from app.yml again and then rebuilding. Maybe this is not enough to do? [image] Sam Saffron: I would run this What is meant by “this”? The sudo ./launcher rebuild app?

I’m using an AWS EC2 “t2.medium” with 2 vCPUs and 4 GiB RAM. The HDD is 100 GiB with 60 GiB of free space. If it helps, I can upgrade “t2.medium” to a larger instance type. I’m just confused that this setup ran rock solid (for years) before my testing of the official AI plugin and only ever since…

Thanks, guys, I’ll google how to do this and then do it :slight_smile:. Update 1 I’ve now added 8 GiB of swap: $ free -h total used free shared buff/cache available Mem: 3.8Gi 290Mi 2.9Gi 1.0Mi 677Mi 3.3Gi Swap: …

This is a bit off topic, but I really would like to understand. Why swap, that used 200 MB, helped when there was 2 GB free RAM? (I understand that in the inch world SI-system can be confusing because it uses 10 scale, but why the heck Mi? I can kind of understand Gi if it is shorted from giga, but…

[image] Jakke Flemming: but why the heck Mi? I can kind of understand Gi Mi for Mibibytes I’d assume, and Gi for Gibibytes.

Thanks. I did not know that, obvious. But it is mebibyte :wink: And for others who didn’t know either :smirking_face: Mebibyte The mebibyte (symbol: MiB) is a unit of information or computer data storage. The mebibyte is closely related to the megabyte (MB). The megabyte refers to 106 …

[image] Jakke Flemming: This is a bit off topic, but I really would like to understand. Why swap, that used 200 MB, helped when there was 2 GB free RAM? I think the original problem was probably a process getting killed because the machine was out of memory (beware the OOM killer). Adding sw…

What’s the spec of your server?

Online upgrades imho require a 4GB server + 2GB swap these days as minimum.
