There is only one user with 64 connections currently so I am going to assume this is your third party CI user (it is NTT SystemFault MasakariIntegration CI). I've gone ahead and closed all 64 existing connections in Gerrit. This is typically caused by ssh clients that don't properly close their ssh connection with gerrit. At one point this happened because of a bug in Zuul. That bug has long since been fixed; you should ensure that you are running an up to date version of zuul and paramiko to avoid this. Firewalls that timeout connections may also cause this to happen. Also for future debugging it helps to get the client name and/or ID so that we can be sure we are identifying the correct accounts and connections on the Gerrit side of things. > > [1] > e.g. "gerrit stream-events", "git-upload-pack <repository path>" > > Best regards, > -- > _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ > Rikimaru Honjo > E-mail:[email protected] _______________________________________________ OpenStack-Infra mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-infra
