Elasticsearch Issue


Recommended Posts

We are having an issue with Elasticsearch - earlier our server ran out of disk space and when checking our core_log database had over 100GB of Elasticsearch errors in it. At some point the disk had got so full Elasticsearch had gone into a readonly mode but I don't know if that was the cause or symptom of the issue.

We have now cleared the logs and made more space on the server so it has plenty and Elasticsearch is running OK again.

We had a gap in the search index so decided to rebuild it in full but, we are still receiving GB's of errors in our logs, the same as the ones we were seeing before we fixed the space issue.

The backtrace is this and several hundred occur every 5 minutes (presumably when the scheduled task runs):

#0 /home/username/public_html/system/Content/Search/Elastic/Query.php(1238): IPS\_Log::log('Array\n(\n    [qu...', 'elasticsearch')
#1 /home/username/public_html/applications/core/sources/Stream/Subscription.php(145): IPS\Content\Search\Elastic\_Query->search(NULL, NULL, 1)
#2 /home/username/public_html/applications/core/sources/Stream/Subscription.php(90): IPS\core\Stream\_Subscription->getContentForStream(Array)
#3 /home/username/public_html/applications/core/tasks/dailyStreamSubscriptions.php(40): IPS\core\Stream\_Subscription::sendBatch('daily')
#4 /home/username/public_html/system/Task/Task.php(367): IPS\core\tasks\_dailyStreamSubscriptions->IPS\core\tasks\{closure}()
#5 /home/username/public_html/applications/core/tasks/dailyStreamSubscriptions.php(41): IPS\_Task->runUntilTimeout(Object(Closure))
#6 /home/username/public_html/system/Task/Task.php(266): IPS\core\tasks\_dailyStreamSubscriptions->execute()
#7 /home/username/public_html/system/Task/Task.php(229): IPS\_Task->run()
#8 /home/username/public_html/applications/core/interface/task/task.php(58): IPS\_Task->runAndLog()
#9 {main}

And this is the error coming back from Elasticsearch:

Nothing has changed within the forum itself and no changes on the server side either that I am aware of.

What is causing the huge amount of errors and how do I fix it please?

Thanks,

Grant

I think I have found the issue that caused this - I don't know enough to know if it is something that could be sensitive - an underlying bug that once triggered could cause other peoples forums who are using ElasticSearch to generate GB's of error log files in the background automatically - how can I report this in a non-public way for investigation by IPB?

I have created a ticket for this purpose, you should have received an email which you can reply with your details. Thanks!
