[Zope] Errors Creeping onto FTP Sessions

[Edward Pollard]

I've recently discovered the most unusual thing with our FTP clients. 
Occasionally, with no rhyme or reason, they cannot retrieve their 
files.

The log is less than helpful.

142.66.35.80 3070 ==> 227 Entering Passive Mode (142,66,6,31,199,202)
142.66.35.80 3070 <== RETR remote_icon.jpg
142.66.35.80 3070 ==> 550 Error opening file.

I'm not even sure what this means. I can FTP in with the same account 
at the command line and successfully retrieve the document.

It seems like my list of problems with Zope is growing long, I'm hoping 
someone can help me prune it.
