[YG Kumar]

Hi All,

We have a wallaby OSA setup. Of late, we have been observing some message timeouts while creating instances.

What could be the cause ? is it a bug ?

[Takashi Kajinami (kajinamit)]

That specific error explains little about the actual cause.

Please check nova-conductor log (with request id req-e6f22565-0973-4e26-8497-b1ee1ee9e1a2) and whether it is peocessing something. You may probably attempt inreasing rpc_response_timeout and check if it resolves the problem.
