I’ve seen this with a site I worked on that <i>had</i> a windows file server that contained uploaded images for a recently large cartoon movie that came out over the summer (any one remember the “stupid donuts” videos on YouTube?) (This was on a Quad Quad Core AMD 64 processor with 16G of RAM and 100G of drive space on a fiber attached SAN, all the system did was file shares.)
This was because we had this number of files in a directory. Unfortunately, to resolve the issue we moved the shared information to a SMB share on a linux system. Mainly becasue I’ve seen several instances where (no matter what tuning you make) windowss doesn’t handle tons of files in a filesystem well. (This coming from a Windows guy).
Any chance the filesystem can be cleaned up or moved into a DFS file share?
