print(f"entrypoint run successfully - {DEPLOYMENT_ENV}-outbound-agent") logger.info(f"entrypoint run successfully - {DEPLOYMENT_ENV}-outbound-agent") cli.run_app( WorkerOptions( _entrypoint_fnc_=entrypoint, _agent_name_=f"{DEPLOYMENT_ENV}-outbound-agent", _prewarm_fnc_=prewarm, port=9000, _shutdown_process_timeout_=15, _request_fnc_=request_fnc, _num_idle_processes_=3, _initialize_process_timeout_=30 ) )

The configuration you’ve shared looks pretty solid, but I totally get how that timeout issue can still pop up sometimes. Let’s walk through some friendly troubleshooting steps to help you get this sorted out: 1. Double-check the Initialization Timeout: The

initialize_process_timeout

is set to 30 seconds right now. If things keep timing out, try bumping it up to 60 seconds just to see if that gives your processes enough breathing room. 2. Keep an Eye on System Resources: Take a peek at your CPU and memory usage while the process is initializing. If your system’s pretty busy, that could slow things down. 3. Look Over the Prewarm Function: If your

prewarm_fnc

is doing some heavy lifting, make sure it’s wrapping up within the timeout window. Maybe there’s some room to optimize it? 4. Check the Logs: Logs can be super helpful! See if there are any error messages or patterns that might give clues about what’s causing the timeout. 5. Try Testing with Less Load: Temporarily lowering the

num_idle_processes

might help you figure out if resource contention is the culprit. 6. Adjust the Timeout if Needed: If your processes just need a bit more time, feel free to increase the

initialize_process_timeout

to better fit your workload. Here’s an example config you can try out for testing:

from livekit.agents import WorkerOptions, cli

opts = WorkerOptions(
    entrypoint_fnc=entrypoint,
    num_idle_processes=3,
    initialize_process_timeout=60,  # Increased timeout for troubleshooting
    prewarm_fnc=prewarm,
)

cli.run_app(opts)

If you’re still running into issues, don’t hesitate to share any extra logs or details about your workload. I’m here to help you get this figured out!
