everytime i try to run the livekit agents, at the ctx.connect() it is giving error -6 process exited

Thanks for reaching out, Mohammed. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

Thanks — I’m responding to your report that

await ctx.connect()

exits with “-6 process exited” while running locally and you’ve shared package versions, logs show normal before the error, keys and network are fine. Given that, try these targeted checks and quick fixes (most likely causes first): 1) Prewarm any heavy audio models (Silero VAD / turn-detector) • If you use Silero or other CPU-bound plugins, load weights before the agent starts so they don’t initialize during connect. Register a

prewarm

that loads models into

proc.userdata

and access them from

entrypoint

before calling

await ctx.connect()

. 2) Disable or isolate local audio I/O • Ensure no synchronous audio operations (e.g.,

sounddevice

play/record) are running during startup. Run a test with audio plugins disabled to see if the crash stops. 3) Enable debug logging to capture hidden exceptions • Add:

import logging
logging.basicConfig(level=logging.DEBUG)

and re-run to capture any exceptions the framework may be swallowing around

ctx.connect()

. 4) Run in a clean virtualenv with slightly different dependency set • Create a new venv and install compatible versions:

python -m venv lk-env
source lk-env/bin/activate
pip install "livekit-agents>=1.3.0,<1.4.0" "livekit>=1.0.0,<1.1.0" websockets==14.1 aiohttp==3.10.10

then run your script to check for dependency conflicts. 5) Check for stray/zombie processes or port conflicts • Kill any previous agent processes before starting:

pkill -f agent.py

or reboot the machine to clear handles. 6) Minimal repro to isolate • Create a tiny agent script that only does model-less connect:

async def entrypoint(ctx):
    await ctx.connect()
    await asyncio.sleep(1)

If that still exits -6, the problem is environmental or event-loop related; if it succeeds, gradually add plugins to see which triggers the exit. If you’d like, paste: • The small snippet around how you initialize

ctx

/

AgentServer

and the

entrypoint

• The debug log lines immediately before the -6 exit I’ll use those to point to the exact failing component and next steps. Sources: Agent server options | LiveKit docs | examples/survey | livekit/livekit_composite | DeepWiki | Job lifecycle | LiveKit docs

no logs nithing is there only exiting is happening with -

Sorry this is blocking you — I’ll help narrow it down. You said there are no logs and the process just exits with -6 at

await ctx.connect()

. A few quick, focused checks and one minimal repro will pinpoint the cause. Please try these in order and tell me which step changes behavior: 1) Add a visible debug print immediately before and after connect

print("DEBUG: before ctx.connect()")
await ctx.connect()
print("DEBUG: after ctx.connect()")

If you see the first print but not the second, the failure is inside

connect()

. 2) Run with Python’s crash trace enabled to capture fatal signals Start your script like this to get a backtrace if a C-extension or native crash occurs: Linux/macOS:

python -X faulthandler program.py dev

Windows:

python -X faulthandler program.py dev

Share any traceback printed. 3) Run a minimal no-plugin connect to isolate plugins Create and run this minimal entrypoint. Replace construction as needed for your codebase:

async def entrypoint(ctx):
    print("DEBUG: minimal entry start")
    await ctx.connect()
    await asyncio.sleep(2)
    print("DEBUG: minimal entry end")

If this still exits -6, it’s environment/auth/SDK related. If it succeeds, a plugin (VAD/turn-detector/tts/stt) is the culprit. 4) Confirm credentials and URL in-process (no secrets) Add prints to confirm env vars are present (don’t paste secrets):

import os
print("LIVEKIT_URL=", os.getenv("LIVEKIT_URL"))
print("LIVEKIT_API_KEY set=", bool(os.getenv("LIVEKIT_API_KEY")))
print("LIVEKIT_API_SECRET set=", bool(os.getenv("LIVEKIT_API_SECRET")))

5) Run with faulthandler + debug logging for the agent

import logging, faulthandler
faulthandler.enable()
logging.basicConfig(level=logging.DEBUG)
# run agent as you do

Copy any output around the exit. 6) If minimal repro crashes, capture a core/backtrace On Linux try:

ulimit -c unlimited
python -X faulthandler program.py dev
# after crash, check core file with gdb to get a backtrace

(Only if you’re comfortable; useful if it’s a native crash.) What I need next from you (pick what you can run quickly): • Output of step 1 and whether you saw the before/after prints. • If step 2 produced a traceback, paste it. • Result of the minimal no-plugin connect (step 3). • The small snippet showing how you create/run the agent (the `AgentServer`/`entrypoint` + how you run

program.py dev

). I’ll use that to identify whether this is an auth/URL issue, a native crash, or a plugin initialization problem and give the exact fix. Sources: Agent server options | LiveKit docs
