Three technical issues on OTB servers

Platform & services
1

Dear all,

We encountered three technical issues on the OTB collaborative development platform.

Issue #1:

On Monday morning, the VM hosting the OTB forum and website suddenly became inaccessible via the network (and it itself no longer had access to the Internet).

After spending a long time searching for the source of the problem in the VM configuration, the hypervisor configuration, and the host configuration, without finding any anomalies, we became certain that the problem was coming from our hosting provider. We were finally able to fix it this evening. As you can see, the forum and website are now up and running again.

Issue #2:

The above failure provided an opportunity to review the configuration of four servers and identify some anomalies and discrepancies. I therefore set about tidying things up and removing obsolete packages.

Working a little too quickly on all four machines at the same time, I made a big mistake that resulted in the destruction of the SonarQube database.

I apologize for this rookie mistake. I’m ashamed. :fearful:

I started the restoration and it was successful, but authentication via GitLab no longer seems to work.

I will look into this and let you know when I have restored it.

Issue #3:

For some reason I haven’t yet identified, the VM hosting SonarQube and GitLab is experiencing significant latency, making these tools difficult to use. I’ll look into this further to try to understand what’s going on.

Situation update:

  • Issue #1: Fixed
  • Issue #2: Overall, it was fixed, but I discovered on this occasion that authentication delegation to GitLab was no longer working. Deleting the SonarQube database does not explain this issue, as I restored it (without encountering any problems) and SonarQube is working correctly. This OAuth2 issue probably predates that. We suspect an incompatibility introduced by a GitLab version upgrade (the forge is regularly updated, while our SonarQube instance is a bit old).
  • Issue #3: I identified a major cause of slowdown and corrected it. The applications still lack responsiveness for my liking, but I can’t understand why, given the resources allocated.
