[Sussex] FC4 - FTP timeout

[Brendan Whelan]

More information on intermittent FTP problem - in the message log there are
lots of "FTP session opened" and "FTP session closed" messages but some odd
errors e.g.

Sep 25 12:21:42 c100091 kernel: audit(1159183302.010:46): avc:  denied  {
write } for  pid=2464 comm="proftpd" name="661600" dev=dm-0 ino=6117997

This pattern matches what is reported i.e. sometimes the FTP works but other
times it doesn't.

I have looked in ProFTPD (for the first time) and see that max instances is
set to 20 - should I increase the value? Is there anything else I need to
change?
