No such file or directory

[Colin Brown]

I am running pyftpdlib under Centos 6 (using default python2.6.6) in a VMWare environment doing file I/O to an EXT3 local disk.

The server is handling a dozen or so connections from one source of 700x 16MB files with currently three clients retrieving the same data via directory soft-links.

The writer is saving a temporary file, attempting to delete the final filename then renaming the temporary file to the final filename.

The reader is reading single named files.

Occasionally ioloop, line 487 in modify is returning IOError: No such file or directory.

My current log has 3 instances all within the same hour:

  1.  Writer to home directory writing temporary file

  2.  Reader from client directory via softlink (same file successfully read 5 minutes earlier and 2 minutes later)

  3.  Writer to home directory writing temporary file
