[ECODP-dev] ODP : troubleshoot issues with production instance

[ISOARD Olivier (OP)]

Dear Tenforce, Okf,

I was finally a bit too optimistic yesterday afternoon when I reported that rolling back to 00.07.01 stabilized the production env. Since yesterday evening, OP is facing exactly the same troubles than with 00.07.05 (recurrent crashes and perf. Drop)

So it means that regarding the testing env to setup on 10F side, I propose to limit the software installation to 00.07.01, in order to be strictly identical to the current OP production. From our side, we’re going to directly collect the logs from PROD, also doing a dump of the PROD database (in 00.07.01). As agreed yesterday afternoon during our telco, I will also prepare a package with as several large dataset zip packages we recently received, for you to experiment the performances problems in RDF2CKAN and CKAN2TS.

I’ll keep you posted when the material for investigation will be ready.

Best regards,

Olivier ISOARD

Hi Darwin,

Thanks for the proposal. We have anyway our weekly telco together with 10F this afternoon. Let’s discuss it there.

Just an update on the current situation:


Ø  The roll back to 00.07.01 is now completed. We applied then there the latest changed we managed last week: Load of DS and user account creation.

Ø  Yesterday after the roll back we still faced drop of prefs & troubles which made us doubting it may come directly from 00.07.05 patch.

Ø  We are still investigating other potential sources explaining the problem: VM, network, visitor traffic on the website…

Ø  What we noted already this morning is that Baidu, the Chinese search engine was crawling the ODP. We still checking whether or not this was also the case last week when the servers crashed several times.

>From you side, could you please have a look at what can be configured, for example in “robot.txt” in order to have a better fine tuning of what can be indexed by crawlers from what we can forbid access without preventing people finding ODP main pages.

Best regards,

Olivier ISOARD

Dear Olivier

I just wanted to reiterate that David and I are available today to assist with troubleshooting.

We are available this morning or this afternoon apart from 15:30 to 17:30 CET.

A goto meeting session with your sysadmin may allow us to pinpoint the issue.

Best,
