Hi Phil,

Thank you for your reply. We have just added size to HD because it was just over 93% and the cache folder is not increasing, it keeps in the same size. We are going to schedule an upgrade of Device Server and Console (the issue is in the Console) to 22.10 version and see if this fix it.  I don't know if the root cause is an IIS performance problem in the server but actually the Event Viewer does not show any suspicious in this way.

Much appreciated!
