Open Stack

Dear everyone,

I am Guy, one of the operator for our third-party CI.

Recently, we are facing an issue in our CI. Indeed, our CI keeps running and reports the results to Gerrit. But there are still some remaining connections to Gerrit that are not closed. OpenStack Infra said that it reaches more than 100 connections (limit number of allowed connections). So when the connection is over 100, our CI cannot connect to Gerrit because the IP is blocked due to the high number of remaining connections.

We are still checking our servers if one of them keeps dropping SSH connections to Gerrit at the port 29418. So far, we haven’t found any servers trying to connect to Gerrit.

Besides, our zuul version is 2.5.2. This version has already includes the fix for https://storyboard.openstack.org/#!/story/2000923.

Is anyone has faced this issue before? If yes, how did you fix it?

Thank you in advance for your answers.
Best regards,
Guy KIM
