memory never empties

[thetuxinator]

Same issue here. Also Docker.

[thetuxinator]

@LiloBzH is your site a high traffic site?

[LiloBzH]

@thetuxinator not really .

11 services
4.5k block requests
92 blocked unique ip
19.3k total requests

~3-4k req/day

These are mostly personal websites, so there are quite a few attacks or hacking attempts. So typical, unfortunately :(

[rrrevin]

Same. 5 services, ~3-4k req/day

I restart my containers every two days, and after a few hours it comes back.

First, I modified the global configuration as indicated in your configuration in order to achieve the following to date:

https://docs.bunkerweb.io/latest/fr/features/#__tabbed_29_3

METRICS_MEMORY_SIZE=64m
METRICS_MAX_BLOCKED_REQUESTS=5000
METRICS_MAX_BLOCKED_REQUESTS_REDIS=500000

I naturally went through several adjustments between the basic configuration and the one currently in use.

On the redis server side, here is an excerpt from the logs.

Hello guys, we are aware of the problem and it will be fixed in the next release.

At the moment, the fix is already in the dev branch / docker tag so if you have some time to test it would be greatly appreciated.

Testing at the moment

[guedz]

I just deployed version 1.6.7-rc1.

I'll get back to you as soon as possible.

While I think of it, is it normal that bunkerweb, after a startup or restart, does not use the persistent configuration in place until the scheduler has finished starting up and injecting the configuration it has just generated? In my case, this cuts off all my web traffic for more than 5 minutes while the scheduler queries letsencrypt to verify the certificates at startup.

Hi guys, as this is strongly related to that issue that was created before (even if the title differ) I'm closing this one as duplicate. Thank you for your understanding.

Looks like still happens, redis gets unresponsive and then it starts to produce that error and the server generates a high load value.
