We have an occasional problem where files written to the server (by either saving from the app or copying) will be incomplete and considered in use. Clients are not warned the file did not write. The files are usually 0 K files that will crash the clients when they try to preview the folder. The only solution I have found is to search the volume for 0 K files and delete them with the sudo rm command, (they cannot be trashed because they are “in use”) then use the lsof command to track down any remaining files and delete them. This happens with either posix or ASL permissions. The server is OS X Server 10.4.8 and clients are 10.3.9. Does anyone have any idea what this might be?
