Does this issue still exist with v4.0.0?

basduineveld commented 1 year ago

We are running v4.4.2 and are seeing the same issue. With every HUP signal, the memory usage increases by about 200 MB, until the pod goes OOM. When we disable the cronjob that sends the HUP signal, the memory usage remains stable at 800 MB for days.

If anyone has a solution I welcome a PR. for me I don't use docker here, i just run tileserver-gl directly in node, but it doesn't seems to have the same memory issues when run that way (at least I have never experienced memory issues with tileserver run directly)
