Hi,

This morning I started to get `system.swap (swap), used swap = 100%`alerts on my Debian 11 node, so I wanted to check it.

I went to the cloud dashboard, and realised that the **netdata agent was offline.**

I tunneled in, and the memory seemed good:

> MiB Mem : 32089.8 total, 4537.2 free, 4100.7 used, 23451.9 buff/cache  
> MiB Swap: 512.0 total, 0.4 free, 511.6 used. 27518.8 avail Mem

I checked the agent, it was active, tried restarting it, stopping, starting, etc, but it was still “Offline” according to the cloud. The alerts stopped after a while, only appeared only once per restart.

I checked ACLK status: `sudo netdatacli aclk-state`

It was offline here as well, and it was always failed at connecting, reconnect count was always zero.

So I checked `error.log`:

It said `ErrUnsupportedAgent`so I checked `buildinfo`:

Why is **binpkg-deb** unsupported now?

I had some issues with netdata before and maybe this node was also problematic. But we fixed it on the forum. Maybe some of the fix flagged this agent in a way that is unsupported now?

How could I fix it, what’s the source of the problem? 😑 Why am I getting swap alerts if there is plenty of free swap according to top?

Thanks in advance! 🙂

Hi @Tudvari

We are sorry, but currently agents with version v1.39.0-97-nightly such as yours have an issue that forced us to prevent them from connecting to the cloud.

The issue will be resolved in the next nightly version. If you wish, you can manually run the netdata-updater script to update, or wait until it runs by itself.

We apologize for the trouble.

We can check though the issue of the swap usage alert, but from your post `MiB Swap: 512.0 total, 0.4 free, 511.6 used` indeed it seems that there is little swap left?

Thanks, I updated it and now it works! 🙂

Regarding the swap alert: shoot, I misread it, and indeed it is nearly full. I just have to find out why, I guess. 😃
