Description:
Hi,

My site went down 3~5 times every single day without any issue such as traffic, CPU utilization, network in or out. I need to stop my instance and start it again to make it work correctly.
Here is the support code outputted by the bitnami supporting tool

Thank you

Hi @asghar.ilmigo,
I can find several errors on your Apache logs.
I would start by this one:

[Mon Oct 28 20:24:20.670651 2019] [mpm_event:error] [pid 1956:tid 140681203345152] AH03490: scoreboard is full, not at MaxRequestWorkers.Increase ServerLimit.

I found information about the issue for example here: https://www.tectut.com/2016/04/workaround-for-scoreboard-is-full-not-at-maxrequestworkers/

Could you take a look to the parameters mentioned on that article?

Hi, I am facing similar issues. The website is going down every day. It started roughly a week ago.

Error: AH03490: scoreboard is full, not at MaxRequestWorkers.Increase ServerLimit.

It seems an Apache issue, but the last version available on AWS is 5.2.2-3 and Apache was updated in the next version 5.2.3-0.

Could you check my configuration, please?

Hi @possani,
The latest version of the bitname Wordpress on AWS is the 5.2.4, you can find it here https://aws.amazon.com/marketplace/pp/B00NN8Y43U
Can you take a look to it?

Hi @mighelaeh,

Can I also use that with Amazon Lightsail? Because that's where I couldn't find that version and the system is currently running.

Hi @possani,
sorry I checked the launchpad not the Lightsail.
Anyway, It seems that your issue is related to the MaxRequestWorkers property of the Apache server, have you tried to increase that property?
