Have other users reported 'race conditions' when connecting a client and agent? My connections do not always connect to a usable voice chat - about 1 in 5 fails - and I am trying to determine where the problem is.

Thanks for reaching out, Craig. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thank you for reaching out. There have been reports of race conditions when connecting clients and agents, particularly in earlier versions of the LiveKit Agents framework. To address this, starting from version 0.8, the framework introduced a requirement to explicitly call
await ctx.connect()
to initiate the connection to the room. This change allows for pre-connect setup, such as callback registrations, to avoid race conditions. If you are not already using this approach, I recommend reviewing your implementation to ensure it aligns with this updated method. If you need further assistance or have additional details about your setup, feel free to share them, and I’ll be happy to help further. Sources: Tree View: | dse-workbench

I am using this approach. Is there anything else I can look at?

Thank you for confirming that you are using the recommended approach. Here are some additional areas you can investigate to troubleshoot the connection failures: • SIP Call Failures: If you are using SIP, ensure the SIP trunk provider is accepting the calls. You can monitor participant events to check the call status. For example, if the
sip.callStatus
attribute updates to "active," the call has connected. • Disconnect Reasons: LiveKit provides specific disconnect reason codes, such as
SIP_TRUNK_FAILURE
,
CONNECTION_TIMEOUT
,
USER_UNAVAILABLE
, and
USER_REJECTED
. These can help pinpoint the issue. • Audio Frame Capture Errors: If you encounter errors like "InvalidState - failed to capture frame," consider increasing the queue size when creating your AudioSource. A larger value (e.g., 1000-2000ms) can provide more buffer room. • Error Types: Look for error types such as
network
,
serverPingTimedOut
,
timedOut
,
joinFailure
, or
invalidState
to identify potential issues. If you have logs or specific error messages, sharing them could help narrow down the root cause. Let me know if you need further assistance!

Hi @ripe-school-55881. Im experiencing a similar race condition problem with the Agents version 1.0. Were you able to solve your issue?
t
Hey there! I totally understand how frustrating race conditions can be, especially in Agents version 1.0. I'm here to help you work through this. Would you mind sharing a bit more about what you're experiencing? If you could tell me about any error messages, logs, or specific situations where you're seeing the race condition, I'll be able to give you the most helpful advice possible. Don't worry - we'll figure this out together!

sometimes the client starts but does not ever reach the agent - no entries are made in the agent log. does the client start and control the room id? is this different from the worker id in the agent? how do I find logs for the client?

I don't have the answer you're looking for. You could also try asking your question: • in one of the other Slack channels or • to https://deepwiki.com/livekit/livekit_composite which is trained on all LiveKit source code If you find the answer, please post it here to help others!
