Crowdsec memory usage grows until OOMKilled

What happened?

I have Crowdsec running on a somewhat memory limited environment, where more than 1GB usage causes it to get OOMKilled. As far I as I understand, Crowdsec should be able to run with less memory.
The memory usage over the last few days looks like this:

Here is an attachment with the output from the debug/pprof:

heap.pprof.gz

What did you expect to happen?

Memory usage to stay at a constant value.

How can we reproduce it (as minimally and precisely as possible)?

The pprof graph seems to indicate this might be something related to TLS settings, so it might be that enabling them in a certain way might reproduce this issue.

Anything else we need to know?

Could you give us some insights to the TLS settings you use, plus how many machines / remediations you use for TLS?

edit: cause all I see is nginx remediation which cant use the TLS settings. Attaching cscli {machines, bouncers} list can give us an overview you can redact any PII.

Sure! Here is my machines list:

The server where the Crowdsec daemon gets oomkilled works as a central service for all these machines running nginx. The nginx machines have the local credentials set to following config:

url: https://debian-crowdsec:8080
ca_cert_path: /usr/local/share/ca-certificates/client_ca.crt
cert_path: /etc/ssl/crowdsec.crt
key_path: /etc/ssl/crowdsec.key

The nginx bouncers run with following type of config:

ENABLED=true
ENABLE_INTERNAL=true
API_URL=https://x:8080
API_KEY=x
BOUNCING_ON_TYPE=all
FALLBACK_REMEDIATION=ban
MODE=live
REQUEST_TIMEOUT=1000
CACHE_EXPIRATION=1
UPDATE_FREQUENCY=10
APPSEC_URL=http://x:7422
SSL_VERIFY=true

I have the same issue that the container goes OOM after a few days. I have the same kind of setup like the OP but then with 1 local and 1 remote firewall agent. The connection is without TLS over wireguard.

I have the same issue that the container goes OOM after a few days. I have the same kind of setup like the OP but then with 1 local and 1 remote firewall agent. The connection is without TLS over wireguard.

Then we going to need some more debug gable information, as it cant be the same as OP when the OP is using TLS and you are not.

You can dump the pprof https://docs.crowdsec.net/docs/next/observability/pprof/ stats to a file when possible also, you can use cscli support dump and this will also collect the pprof metrics for us.

Remember to include any information like custom scenarios or profiles as before when we had people complaining about OOM they were using custom scenarios that were not optimized and were collecting hundreds of events and keep in mind all events are stored in memory until overflow.

I also have that issue, but for me, it is the AppSec container that OOM's.

From my (daily rebuilt) DEV environment (from which I got the support dump as well):

crowdsec-support.zip

[LaurenceJJones]

Thanks for the report and the extra context.

1. AppSec can use more memory than other containers because it must read the request body before handing it to the underlying engine. This is expected for many WAF rule sets that inspect full bodies. We are evaluating improvements in this area (see enhance: Attempt to reduce body reads on appsec #3805), but if your rules require body inspection the gains may be limited.

2. Please ensure your web server is enforcing a reasonable maximum request body size for your use case. Many servers default to around 100 MB, which is far higher than typical API traffic needs. If you do accept large uploads, consider:

   • Limiting large bodies to dedicated upload paths
   • Skipping or relaxing body inspection on those paths
   • Using separate upstreams for upload endpoints

3. We cannot reproduce the OP reported OOM so far. To help us debug your environment, please share:

   • Pprof captures (heap, profile) around the time of the spike

4. Mitigations you can try now for AppSec:

   • Set a tighter max request body size on your front end (for example, NGINX client_max_body_size 5m; if 5 MB suits your workload)
   • Exclude static assets and health checks from AppSec inspection
   • Scope the most expensive body rules to only the endpoints that need them
   • Allocate conservative memory limits and monitor usage to avoid kernel OOM kills while we analyze pprof data

[schnurrro]

With further analysis we found out increasing the chart version fixed the problem.
Here are more details about it:

• Both Appsec and LAPI pods show memory usage increase over time.
• Appsec pod restarts periodically, which resets its memory usage and also frees up memory allocated by LAPI.
• This behavior is linked to constant communication between Appsec and LAPI.
• CrowdSecMode is set to appsec which is mandatory for our setup.
• Using cscli support dump a zip file can be generated containing various information including pprof heap data.
• Thread about memory consumption with bouncers and appsec component enabled, caused by communication between LAPI and appsec, see here.
• Our crowdsec core version was v1.6.9.
• Our helm chart version was v0.19.4.
• Pull Request on optimizing communication: enhance: appsec reuse httpc optimization #3693
• Patch merged and released with crowdsec version 1.6.10, see releases
• Crowdsec version 1.6.10 is used in kubernetes helm chart version v0.19.5 (latest)
• Our helm chart was upgraded from v0.19.4 to v0.19.5.
• No more memory increase in appsec pod

---

Here are the memory usages of the pods in our dev environment in which we tested:

Appsec pod memory usage with v0.19.4 deployed captured on on 22.08.25:

LAPI pod memory usage with v0.19.4 deployed captured on on 22.08.25:

LAPI pod memory usage with v0.19.5 deployed on 26.08.25:

The LAPI pod memory usage is still slightly increasing, this needs to be observed over longer time frame.

Appsec pod memory usage with v0.19.5 deployed on 26.08.25:

Thank you taking the time to look into it @schnurrro

Glad to see some changes improve appsec, I am working on some other optimizations such as:

#3801
#3805
#3878

which means it will get better overtime, but some are drastically changing how the component functions.

The LAPI can periodically have spikes due to this component being the one in charge of downloading blocklists and other remote content, but >1gb is alot. Due to you have a lot of Remediation Components (bouncers)?

[schnurrro]

Yes we have three bouncers in total:

• Two linux fw-bouncers to block threats right at the entrance to our systems
• One traefik bouncer working together with appsec
