All, Gerrit seems to be in a bad shape. Pages load minutes, if at all, pushes are impossible to make. Could you please check this? Thanks, Marcin

git fetch/push slowliness and/or errors
by Yevgeny Zaspitsky 04 Apr '16

04 Apr '16

Recently (today) I started having problems with pushing and fetching staff from oVirt git server. Bellow is what I get on my attempt of pushing the rebase topic: [yzaspits@yz-dell2 ovirt-engine]$ git push gerrit.ovirt.org:ovirt-engine HEAD:refs/for/master/ipv6 Counting objects: 1275, done. Delta compression using up to 8 threads. Compressing objects: 100% (515/515), done. Writing objects: 100% (1275/1275), 164.53 KiB | 0 bytes/s, done. Total 1275 (delta 540), reused 1060 (delta 341) remote: Resolving deltas: 100% (540/540) remote: Processing changes: updated: 15, refs: 16, done remote: error: internal error while processing changes To gerrit.ovirt.org:ovirt-engine ! [remote rejected] HEAD -> refs/for/master/ipv6 (internal error) error: failed to push some refs to 'gerrit.ovirt.org:ovirt-engine' The command run took about 5-10 minutes, during which was very slow progress in the "updated" count. Fetching takes very long time too. I tried pinging gerrit.ovirt.org but didn't find a problem in the network. Also ssh -T works relatively fast. Is anyone experiences anything similar? How can this be troubleshoot? What "internal error" does mean? Is that on the git server side or on the on the client one? Regards, Yevgeny
