Thanks so much for your reply.
Re; your reply:
Could you share how you setup the Kolibri servers at your centers?
We run Kolibri on Ubuntu 16.04 LTS, and installed via PPA Repository. After installing kolibri, I add the kolibri user into the sudoers file. I give kolibri user ownership of the .kolibri folder. Thereafter import the content etc.
This is done once, the rest of the server gets cloned.
Were the different servers setup at the same time using the same method, or were they done differently?
There’s no difference, all cloned from one image.
What version of Kolibri did you have before the upgrade?
These server were on v10.2
Some where on 9.2
Could you tell us if anything happened recently before you started having these problems?
Nothing Critical that made it unresponsive as this, mostly some content was taking long to load, some was taking long to login.
I notice that the logs go back several months; were things working okay then?
Yes we have received several monthly CSV reports from our centre’s. We even have a center from Cricket SA who has a centre for young players to study after school
Did the problems occur immediately after upgrading to 0.11.
Yes, the first centre that started using it, called the same day they switched it on. that was from the centre I spent an hour on the phone with this morning, testing different scenarios, like testing network, to see if the disconnection is caused maybe from the Access Point, the connection remained stable with 0% loss of packets. No error logs on the router logs.
Today we asked the users to login 5 at a time, so that we don’t distort the application with requesting to login at the same time, while we monitor the performance on the server as well. We had to ensure that the server is not running out of Memory, while users start logging into kolibri and accessing content, the server was basically under used.
Thank you kindly for your reply. Truly appreciate it.
