Hanging Apache requests using Ubuntu AMI on EFS volume
Solution 1:
I finally found the solution.
The problem happens only in kernels "5.4.0-1029-aws" and "5.4.0-1032-aws". The issue seems solved in "5.4.0-1034-aws" and "5.4.0-1035-aws" kernel versions.
So, you just need to upgrade the kernel:
sudo apt-get-update
sudo apt-get install linux-image-5.4.0-1035-aws
Then, after reboot you should have the new kernel in place. Check it with the following command:
uname -r
You should see this result:
5.4.0-1035-aws
Then you should not have latency anymore.
