Watching for more than 3 pods doesn't work

[ghost]

Hello.
I found some correlation between pods count and ksync watch status.

Here is a my config:

apikey: ksync
context: "mycontext"
daemonset-namespace: kube-system
docker-root: /var/lib/docker
docker-socket: /var/run/docker.sock
log-level: info
namespace: pr-22572
output: pretty
port: 40322
syncthing-port: 8384

spec:
- name: monolith
  containername: ""
  pod: ""
  selector:
  - app=pr-22572-monolith-monolith
  - ksync-role=web-shared
  namespace: pr-22572
  localpath: mydir/monolith
  remotepath: /project
  reload: true
  localreadonly: false
  remotereadonly: false

When I have 4 pods in deployment, 3 of them are in sync, but one is not:

### Ksync status: ###
    NAME      LOCAL      REMOTE     STATUS                            POD                           CONTAINER
-----------+----------+----------+----------+-----------------------------------------------------+------------

                                   watching   pr-22572-monolith-monolith-web-7df599c968-jllbc
                                   watching   pr-22572-monolith-monolith-web-69bd84785d-lz6zl
                                   watching   pr-22572-monolith-monolith-web-7df599c968-xjgpc
                                   starting   pr-22572-monolith-monolith-web-69bd84785d-bxfmz

### Kubernetes pods status: ###
NAME                                                  READY   STATUS    RESTARTS   AGE
pr-22572-monolith-monolith-web-7df599c968-jllbc       1/1     Running   0          31m
pr-22572-monolith-monolith-web-7df599c968-xjgpc       1/1     Running   0          5m51s
pr-22572-monolith-monolith-web-69bd84785d-bxfmz    1/1     Running   0          31m

If I set 3 pods for deployment, the synchronization works fine, and all 3 pods in watching state.
I tried to reproduce it a few times and always when I have 4 or more pods in deployment, some of them couldn't be in the watching state.

In ksync watch output I can see a lot of:

time="2020-10-02T18:08:32+03:00" level=warning msg="Get \"http://localhost:8384/rest/events?since=11585\": dial tcp [::1]:8384: connect: connection refused"

I tried to find some settings for increasing "parallelization" but didn't find it. Maybe this is some issue with GRPC?

Thanks.

It shouldn't be a limitation. Thoughts @grampelberg ?
