roadrunner consuming 100% cpu

[rickgarcia-lfg]

Before creating a bug, I wanted to see if there was anything suspicious with my rr.yaml file. One thing that I notice is that after running for a couple days, my road runner process eats up 100% cpu of a core 100% of the time. It never recovers until I restart road runner. Even tho it is consuming an entire core, it seems to be serving traffic just fine. So it's not creating a service outage or degradation of services, but it is costing $$$ since I run it in a serverless environment that scales up based upon cpu usage.

I am running Laravel, using https://github.com/roadrunner-php/laravel-bridge.

Here is my rr.yaml:

version: "3"

server:
  command: "php ./vendor/bin/rr-worker start --relay-dsn unix:///tmp/rr-relay.sock"
  relay: "unix:///tmp/rr-relay.sock"
  relay_timeout: 130s

http:
  address: 0.0.0.0:9000
  middleware: ["static","gzip"]
  pool:
    max_jobs: 25
    num_workers: 16
    supervisor:
      exec_ttl: 130s
      max_worker_memory: 256
  static:
    dir: "public"

status:
  address: 0.0.0.0:2114

Please let me know if there is something fundamental here that would cause the roadrunner binary to spin out of control... If not, maybe someone can help point me in the right direction for troubleshooting this.

Thanks!

Hey @rickgarcia-lfg 👋🏻
By RoadRunner, do you mean the exact RR process or RR workers?

[rustatian]

It's hard to say what is happening... 😢
Well, unfortunately we don't officially support Laravel (our package) anymore.
It is better to use Octane, but Octane support is super limited and only HTTP plugin (no Queues, Temporal, gRPC, KV, etc) is supported.
For 100% support, please use SpiralFramework.

But still, I would be happy to help you, but you need to do the following:

1. Run RR with the -d option. rr serve -d [your options]. This is internal profiling mode.
2. If you see this behavior, collect the CPU trace: curl "http://127.0.0.1:6061/debug/pprof/profile?seconds=180" --output roadrunner.pporf from the RR. =180 means seconds. I think 3 minutes would be enought.
3. Attach the trace here.

Would you want me to recompile with debug symbols on as well?

You can do this, but it is not required 😃
