We have a single Traefik pod running with Let's Encrypt to generate the certificates. It has limits of `6Gb` of RAM, `3000m` of CPU and its running in a isolated node (nothing else runs in the same node). The node has a disk of `50Gb`.  
We were running `v20.8.0` at the time of the incidents.  
In that cluster we have three important services, **influxDB** , **Artifactory** and **Sentry**

For the past **76 days** the Traefik pod was running without issues.  
Yesterday we had an incident where **Traefik** filled the **RAM** of the pod and then filled the **disk** of the node and then crashed.  
At that moment it wasn't doing anything out of the ordinary. Artifactory and Sentry were running as usual and InfluxDB has a live sync stream and a batch job.  
When we stopped the batch job Traefik started to work normally again.  
Then we re-launch the job again and run without problems for 4hs after a while Traefik crashed again.

For the first measure, we jumped to the latest Traefik `v23.0.1`  
We are trying to move to a HA configuration with **Cert-Manager**. But at the same time we are exploring other options.

My question would be, modifying the `memResponseBodyBytes` and `memRequestBodyBytes` could help with this issue?

- memResponseBodyBytes - [Traefik Buffering Documentation - Traefik](https://doc.traefik.io/traefik/middlewares/http/buffering/#memresponsebodybytes)
- memRequestBodyBytes - [Traefik Buffering Documentation - Traefik](https://doc.traefik.io/traefik/middlewares/http/buffering/#memrequestbodybytes)

Thanks
