Description

Who is this host?
I'm not able to access to this host: ip-90-147-166-112.ct1.garrservices.it

Please could you give me access? We should understand why there are a lot of connections opened from this host to the following host:

node66.p.d4science.research-infrastructures.eu:8080

It's the IP address that's used by the hosts without a public IP. So there's one (or more than one) of the private IP dataminer that went crazy.

Could I have access to this VM? Otherwise the next month I'll ask you the same question: who is this host?
Maybe yes, there is a crazy dataminer behind this host. I need further analysis.

I've verified the logs on all the dataminer instances with private ip. I see the same exceptions found on ckan-bb1, at the time when the IS-Collector was restarted. In attachment the log of dm-192-168-100-6 instance.
Maybe it's better to try to restart these containers in order to improve (I hope) the IS-Collector performance. What do you think @andrea.dellamico@isti.cnr.it ?

Go on. One at a time, you can restart each one.

If the connections problem persists, we can even restart all the dataminers once a day. If we restart the service only when no jobs are running, there's no risk of breaking anything.

OK. I'm going to restart the services one at a time

The services have been restarted. Now I see 0 opened connections from 90.147.166.112. I'm going to close this ticket.
