chrome-headless zombie processes

[fbartels]

Hi,
I am currently debugging a wordpress installation which seems to drag my server down. While debugging i noticed that i had quite some zombie processes which seem to originate from the Linkwarden app. Has anybody else observed something similar?

You can see if you have any by running ps -eo pid,ppid,stat,comm | grep '^.* Z'?

Yep, the same here, 126 zombie processes:

After stopping the Linkwarden app:

How much memory is default?

Any OOM messages in the logs?
