Hello All,

Thank you for the detailed explanation.

@Victor : So if I understand correctly we need to suggest customer, just to set  max_overflow = 50 in cinder.conf, please correct me of I am wrong.

Yes, but also try to reduce the number of cinder-api processes: the osapi_volume_workers option of cinder.conf.

Michael Bayer: "The ps listing shows that there are a ton of cinder-api processes running - osapi_volume_workers in cinder.conf is....48!"

Hello Victor,

Thank you for your response. I have shared the feedback to the customer and have asked to monitor if the issue is still reproducible under heavy load.

I will share feedback from customer when he comes backs.

This issue seems to be a configuration issue, more than a bug. What is the status of this issue? Can it be closed? Or do we have new data to elaborate on the bug aspect?

Comment 31 Victor Stinner 2018-06-05 13:50:55 UTC
I close the issue since it didn't get any concrete data since last year, and my NEEDINFO didn't get any reply since 2 months.

Comment 32 Victor Stinner 2019-09-26 15:31:34 UTC
(I just removed an old NEEDINFO, the issue is already closed.)
