Increased CPU load when idle

[Millisman]

Describe the bug

The program creates unnecessary load on the processor during idle time, as well as during synchronization with the client.
In addition, traffic is created on the lo interface (more than 1 TB per day)

Steps to reproduce

1. Download OpenCloud 2.2.0 latest binary version.
2. Repeat my instance settings

Expected behavior

The program must use resources when actually running.

Actual behavior

The program loads the processor evenly across all cores when doing nothing. The load level is within 15-30% on each core. In addition, it creates lo on the internal interface at a speed of 30MB/s

Setup

As an SSL terminator I tried nginx or mox programs that work on ports 80 and 443. They perform SSL termination and forward traffic to port 127.0.0.1:9200

Additional context

The system log is filled with messages like this:

Operating system - Archlinux latest version, which corresponds to working on "bare hardware" on VM

@Millisman This looks like #716 which is already worked on.

@aduffeck @dragotin

[aduffeck]

Yes I agree, this indeed looks like #716. Let's close it for now. Please reopen if you still see that behavior after #716 has been fixed.
