Kong 3.7.1 Exponential memory growth over time. #13553

Open muh-kamran opened 3 weeks ago

muh-kamran commented 3 weeks ago

Is there an existing issue for this?

Kong version ($ kong version)

3.7.1

Current Behavior

We recently upgraded from 3.3 to 3.71. In last 8 days the memory of proxy grew from 550MB to 1.03GB and eventually got OOM killed. we didn't saw this issue on 3.3.

Nothing changed from our end.. just version upgrade. Please inform me if you need more details. Additionally, I would appreciate any recommendations for debugging steps, areas to investigate, or configuration changes that have successfully addressed similar issues for you.

Expected Behavior

kong 3.3 its much stable:

Steps To Reproduce

No response

Anything else?

only error message in logs i see is: [error] 1437#0: *582289 [lua] http.lua:962: request_uri(): closed, context: ngx.timer

Hi @muh-kamran ! That looks concerning! We should definitely investigate further. Could you please share a little bit more info about your configuration?

Sharing this data will allow us to create a similar environment to yours and potentially replicate this issue.

muh-kamran commented 2 weeks ago

we are using kong as ingress as well as gateway. In gateway we push declarative configuration through admin api.The issue is on both but very aggressive on kong ingress. let share the detail of ingress.

One thing to note this configuration have impact on memory:

    effectiveSemver:
  installCRDs: false
  env:
    enable_reverse_sync: false
    update_status: false
    PROXY_SYNC_SECONDS: 600

when enable_reverse_sync: true and PROXY_SYNC_SECONDS: 30 .. the proxy got OOM killed immediately in few hours. setting it to enable_reverse_sync: false and PROXY_SYNC_SECONDS: 600 or so .. The memory grow slowly and proxy got OOM in days. Could be memory leak on configuration push to admin api.

We found similar issue kong 3.0, just by frequent GET requests to admin API. But it was fixed in 3.2 https://github.com/Kong/kong/issues/10782

chobits commented 2 weeks ago

hi @muh-kamran We need some detailed information to help us identify where the memory consumption is happening. You could run the following commands to get the stats .

  1. whether the memory is consumed in kong's lua land from admin_listen
    • if you are using hybrid mode to deploy, and you want to get info from Data plane, you need to enable status_listen, and run command curl <status_listen_ip_port>/status
$ curl localhost:8001/status
  1. show us the heap map of kong(nginx worker process)
$ cat /proc/<nginx-worker-process-id>/maps
  1. show the open fd of kong (nginx worker process) to see whether there are some leaked connection
lsof -p <nginx-worker-process-id>

or 

netstat -np|grep nginx

or any information which you think is helpful for troubleshooting

bungle commented 2 weeks ago

The growth here doesn't look exponential to me, but quite linear. Also at the end it seems to drop (is that the OOM kill). Am I correct? OOM kill seems to happen pretty close to 1.1GB whereas 3.3 you got somewhere around ~1GB? Or do you mean the hikes in graph look like double each time?

muh-kamran commented 2 weeks ago

Yes, it's experiencing OOM. We increased the memory to 5GB, but it still hits the OOM state in about 2 hours. This time, the memory grow quickly because we changed these two flags on the controller to:

    enable_reverse_sync: true
    proxy_sync_seconds: 2

muh-kamran commented 2 weeks ago

I'll provide the requested details. However, before doing so, I was testing it on a local kind cluster and observed the same pattern with a single ingress object. Here are the steps to reproduce:



- Next i port forward to grafana and run `sum(container_memory_working_set_bytes{container=~"proxy", container!="", image!=""}) by (pod,container)`
