Random guess: flush is a method called on a socket. If a connection
attempt is being refused by the Jabber server due to rating or karma,
which might be the case here ("consistently fails on the 3rd login"),
then that socket might not actually exist in Perl space, hence the
undefined value. 

To test out this theory, stick some sleep statements in there, also
check the error.log from the Jabber server for indications of 
socket limiting etc.

What version of XML::Stream are you using? There's a flush call on
line 1258 in 1.12 of XML/Stream.pm ...
