Note: if that's a MemoryError[1], it may be caused by *any* memory leaks 
within the python process (the server). And then, the memory error will just 
appear at a random trace. In the code you mentioned, the "e" variable should 
just need a few bytes, so it's highly unlikely that the poll() function 
received bad arguments.

Although, I believe that FTP (in the v5.x series) suffers from heavy memory 
usage itself, because it tries to load the whole data chunk in memory before 
sending it. That, /may/ be linked to the MemoryError, but we cannot be sure it 
is the real cause.
This has been improved in v6.0, for FTP and WebDAV (still, not for RPC 
transfers of files). It is an API design issue so it _cannot_ be backported to 
v5.0 .
