Hi,

Unfortunately, I haven’t been able to move the investigation much further.
I have been running those tests on machines with higher amount of RAM than 4GB, but with hugepages set there to 1GB and using the script provided by Lincoln.
For several runs red_autotest tests didn’t fail even once, not giving any clue what might be the cause of what’s happening on CI.

+Adding Marcin Danilewicz
To let you know, Marcin Danilewicz will be taking over my tasks, so for any further aspects please include or direct messages to him.

Best Regards,
Wojciech

Ok, thanks Brandon for the tip :)
Let’s see if I can setup the machine with such configuration.

Cheers,
Wojciech

Hi,

Thanks Lincoln, I will also have a try with such script.

Hello Wojciech,

I also recommend trying to run the test with around 4GB of RAM and 2GB of hugepages to see if it fails. That is roughly the number of resources we have per machine that is completely dedicated to unit tests. The amount of RAM available can sometimes increase depending on how many jobs are running per machine, but 4GB is the lowest it can go for the unit test job.

Thanks,
Brandon
