I’ve adjusted the setting and see this in the container:
```plaintext
root@ip-10-4-2-52:/# set|grep SIDE
UNICORN_SIDEKIQS=1
UNICORN_SIDEKIQ_MAX_RSS=1000
```
But I see this in the logs:
```plaintext
Sidekiq is consuming too much memory (using: 535.10M) for 'site', restarting
```
It would seem like 535.10M \< 1000, right? I feel like I must have a typo or something else really silly.
This is a very busy site with 600-800K pageviews/day with 7 (largely idle) web containers running in ECS.
There are 4 CPUs in the task, should I increase `UNICORN_SIDEKIQS`?
If I run `[ENV["UNICORN_SIDEKIQ_MAX_RSS"].to_i, 500].max.megabytes` in rails, I get `1048576000`, so it seems like Rails should have access to the ENV, but maybe running rails myself is somehow different from the one that gets cranked up on boot?

it looks like you are doing the right thing… if you raise `UNICORN_SIDEKIQS` to 2 do you see 2 sidekiqs?

I’ll try increasing the number of sidekiq next, but I’m confused that it says 538 mb is to much when it’s set for 1000.

Agree, just want to see that at least one of the env vars is “sticking”

Was there any resolution to this, as I see in my logs:
Sidekiq is consuming too much memory (using: 501.37M) , restarting
UNICORN\_SIDEKIQ\_MAX\_RSS: 1000
and the site is not a very busy one
What else should I try?

Is this a Sidekiq issue, and whether it is nor not, will this issue be fixed?

@sandra.mccollum I also have [a similar issue](https://meta.discourse.org/t/sidekiq-is-consuming-too-much-memory-using-522-12m-restarting/385130).
Were you able to solve?
