I can't analyse this now, b/c I don't have the logs any more.
We did not wait for two weeks there was a Jira malfunction that made ticket-opening mails to reach the right place for the last two weeks up until a few hours ago.

If this was any real infra issue we probably have already resolved it back then. If it is a repeating issue we probably have other tickets about it.

There is no information on this ticket that I can investigate any further.
(An no, just the Jenkins exception is NEVER enough, the real reason is typically a few scores of lines above it)

This seems reminiscent on OVIRT-938, I wouldn't mark this as duplicate though b/c we're not talking about vdsm check_merged here.

I reported the issue immediately as it happened. Waiting 2 weeks until a ticket is reviewed, and then closing it due to its old age is a sure way to keep the low trust the developers have in CI.

We NEED trustworthy CI. We cannot have so many false failures. I'm asking everybody not to rant about these failures, but to report them, so CI can become worthy of its name.

Please consider finding the root cause of this (and all other issues we report). I understand that not every problem can be solved, but an attempt is required.

This seems to have happened a long time ago, please repoen if problem resumes
