Occasional bug, after livekit has been running for a week, room creation error: could not find any available nodes

[keaipeng123]

livekit version:v1.5.3
Program code
if _, err = core.RoomClient.CreateRoom(context.Background(), &livekit.CreateRoomRequest{
Name: rn,
EmptyTimeout: 10 * 60, // 10min
MaxParticipants: 10,
Metadata: owner + "-" + skill,
})

I have a similar message when i try to create a room with livekit-cli create-room
twirp error internal: could not create room: could not find any available nodes

Still couldn't figure it out.

what does the machine utilization look like? including CPU & memory. Could you give the latest version 1.6 a try to see if it still can be reproduced?

[keaipeng123]

Okay, so when this happens, I'll take a cut of the cpu utilization and send it here. I will also give version 1.6 a try.

[keaipeng123]

Since the last time I asked this question, I have had this problem again. The cpu usage is not high in the normal range.
