[Bioperl-l] Fh::flush warning

Could you give a bit more info (bioperl version, OS, etc)?

I'm guessing a recent version as the error coincides with a call to  
flush() in Root::IO (which is probably called indirectly via DESTROY)  
and that you're probably using a tied filehandle somewhere for  
output, e.g. Bio::AlignIO::newFh() or Bio::AlignIO::fh(), so knowing  
the input/output formats could help.
