[horde] Horde VFS on separate DB machine?

[Graeme Wood]

I've also got a problem with some attachments not being uploaded and then 
appearing as zero length when the messages are sent.  It doesn't make any 
difference whether it is a clustered service or not, as we have both one 
service made up of multiple web front-ends and one which is a single 
web front-end.  I also am using just the file system to store uploaded 
files, but there is no NFS. The behaviour looks like either a failure in 
PHP to create the temporary filename or a race condition which means that 
the filename isn't there when the compose.php looks for it. We get errors 
logged in the apache logs to say that the temporary file doesn't exist.

I'm not sure when this problem first started occuring as we have only in 
the last few months started getting reports about this.

I'm running Horde 3.1.3, IMP 4.1.3 and PHP 4.4.7.
