Page view spike in the last minute for Realtime on All Sites

[nfn]

Hi,

I have multiple sites sharing the same installation and whenever I go to Realtime for All Sites I get a huge spike in the last minute:

16:10: https://i.ibb.co/yVrdxZb/1.png

16:16: https://i.ibb.co/G2QD1XG/2.png

16:20: https://i.ibb.co/5jPpLRQ/3.png

The values per site are ok, only when seeing All Sites I get this.
I'm using 1.25.0 installed from source.

Thanks

I've never seen that before. Are you saying if you go through each website, none have stats that high?

None of the sites had spikes that justify this.
The strange thing is the 10:10 spike goes away when I refresh the page at 16:16 and the 10:16 spike goes away when I refresh the page at 10:20.

I'm monitoring this at the moment and I'll update this issue.
These sikes are not regular. The last days the behavior was correct.
