Hi there,

The application errors that you are seeing are probably unrelated to the software update banner. Running the latest version of AtoM is our recommended practice but it's not strictly necessary.

If you send us more details about the errors you are seeing we might be be able to help you. You can find detailed error events in the web server error log. We explain how to access to the error log here: https://www.accesstomemory.org/en/docs/2.3/admin-manual/maintenance/logging/#web-server-logs.

Regards,

Hi there,

I agree with Jesus that the errors are probably unrelated to the update banner, but if you want to turn off the notification, you can do so via Admin > Settings:

https://www.accesstomemory.org/docs/2.3/user-manual/administer/settings/#check-updates

Jesus has already sent you the link for accessing the webserver logs, but you might also find videos 4 and 5 useful from our command-line tutorials: video 4 covers checking the error logs and other debugging tips; video 5 covers some of the most common command-line tasks used to troubleshoot issues.

Hi there,

Your error log indicates a problem connecting to Elasticsearch. That mostly happens because Elasticsearch crashes because it ran out of memory. There was a similar discussion thread in this forum where the same issue was solved:

[...] the reason why Elasticsearch dies unexpectedly is mostly because the JVM has not enough memory assigned. The size of the heap is declared in /etc/default/elasticsearch, e.g. you could try "2g" if you have two GB of memory available. Once the value is changed you have to restart Elasticsearch. There are more details here: https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html.

Regards,
