Hey there.

Have you checked that you’ve assigned enough RAM?

I just checked the host memory usage:
(these are in GiB)
total used free shared buff/cache available
Mem: 7 4 0 0 2 2
Swap: 7 0 7

and also checked the container stats:

CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM %
contaienr_id sonarqube 0.59% 1.476GiB / 7.769GiB 19.00%

NET I/O BLOCK I/O PIDS
405MB / 598MB 153MB / 198MB 195

OS: Red Hat Enterprise Linux 8.6
also my docker engine version is 20.10.6

@Colin : Can you please help.
