Critical Bug and Memory Leak
**I am using this proxy for almost 3 years, there is a bug!** 

The bug description is:

When you have a large number of connections, the proxy becomes unstable and have a big memory leak, 

let's say we have 1k Active connections ( Press C ) it's will print something like:

**[2021-10-20 13:30:54.580] * upstreams active: x sleep: 0 error: 0 total: x

[2021-10-20 13:30:54.581] * miners    active: 1xxx max: 1xxx ratio: 1:xxx.xxx**

but when Show The workers ( Press W ) you could see There Are 3 or 4 k Connections ( and you know well you have only 1k Connections )

**WORKER NAME             | LAST IP         | COUNT | ACCEPTED | REJ |  10 MINUTES
 |    24 HOURS |
XXX                     | xxx.xxx.xxx.xx8  |  4xxx |     xxxx  |   x | xxxx.xx kH/**

The Problem in v6.15.1
