But this does not explain why I get 10.000 of these requests every second, at the same second that I enter the share. Nothing on the server is being written/updated that much, and this is happening around the clock, in any directory on the server. The server is not that busy, and this starting happening from day to day. I tried creating a "temp" folder, moving all folders and files to that folder in the same share. It continued to happen even after I moved all the data there, even though no applications or clients should be able to read/write to anything. Is there any way to enable some kind of verbose debugging to see what is actually happening here? kind regards, Kasper > > On 04/13/10 06:19 AM, Kasper Bræmer-Jensen wrote: >> >> Hi, >> >> First post here, but I've been lurking zfs-discuss the past 3 months. >> >> I'm having a very strange problem with one of my CIFS shares.
