When using kubernetes, this error can be caused by a wrong memory notation in deployment settings.

Update 2021:

New answers in the below-linked thread assert that they have found solutions. See this answer, for example.

Original Answer:

This is a known feature.{1}

The solution that worked for me was to restart the server instance.

In Plesk:

1. Tools & Settings (from side menu)

2. Server Management (2nd grouping on left side)

3. click on Restart Server

Answer 4

For CentOS users, setting max_user_namespaces can be done as follows.
echo 15000 > /proc/sys/user/max_user_namespaces https://superuser.com/a/1294246/1640737

Answer 5

I solve it by upgrade the linux kernel from 4.15.0-202-generic to 4.15.0-206-generic #217-Ubuntu.

My docker --version is 20.10.17, build 100c701.

• 1, install the newest kernel: sudo apt-get install -y linux-image-generic
• 2, reboot the server

Tips: check your environment will be suitable for the newest kernel before install it !
