Can you check the state of the gateway via kamctl dispatcher list?<br>

<div dir="ltr">Daniel. I added 8 algorithm to our server and it
works with 2 servers now but it works strange because:<br>
While works server with priority 1 - all ok. When this server
goes down dispatcher choose next server with lowes priority. But
when server with highest priority waking up dispatcher use
server with lowes priority until this server not goes down.</div>

You probably look for priority based

dispatcher module.<br>

- we find dispatcher algorithm
than can do mechanism
something like this:<br>
Try call to fist server with
max priority or weight. OIf
this server unavailible then
call second server with less

Does anyone know what ling of
