A folder in a namespace takes several minutes to open (from HCP namespace GUI) - what can be the cause ? - its not very big = 334 MB, 2463 objects largest object = 6 MB. Content verification service finds no errors.
Just to try to isolate the problem, have you tried accessing this folder by other means - say, using HCP-DM?
Yes we were about to export/import the folder via HCP-DM, but the problem dissapeared in the meantime. So we'll try this if the problem turns up again. Thanks !
