Dear Bastiaan, Darwin,****

** **

>From the point when we upgraded the production env with release 00.07.50,
we face troubles and crashes with CKAN (several times a day this weekend).
This morning, we already restarted it 2 or 3 times! It looks that something
goes wrong with 00.07.50 and is linked to data volume as we didn’t had
equivalent issues on test (where there are less dataset).****

** **

So, what we’re going to do:****

** **

*A/ Stabilize the PROD env - TODAY:*

* *

**1.       **We will roll back to release 00.07.01, using the last backup
we did the night before the installation of 00.07.50 (Sunday 24/02 night)***
*

**2.       **We will re-import on prod datasets which have been ingested on
prod from last Monday 25/02, in order to update the rolled back env with
latest data****

** **

*B/ Investigate the issue with TEST env - TODAY:*

* *

**3.       **Keeping testing env with 00.07.50****

**4.       **Loading an equivalent volume of dataset in there, using ESTAT
and the archive of prod we have****

** **

*C/ Coordinate investigation with 10F/OKF*

** **

**5.       **Activating additional debugging and logging mechanism for
collecting from TEST detailed information about internal activity of CKAN
(How to ?)****

**6.       **Provide you with logs/debug info for you to investigate
further the problem.****

** **

If you already have instructions and guidance for switching TEST env in
debug mode, they are welcome. Otherwise, thanks to prepare them for
tomorrow afternoon the latest (next weekly telco), where we will do a new
status all together.****

** **

Best regards,****
