Cufflinks displaying "WARNING: Multi-Hit not found"

I'm running Cufflinks (2.2.1) on a set of RNA-seq alignments that I did with STAR. I'm using these options:

/home/user1/Data/Softwares/cufflinks-2.2.1/cufflinks -p 6 -u -o ./Cufflinks/ERR036348_pass-2 ./Alignments/ERR036348_pass-2/ERR036348_pass-2_Aligned.sortedByCoord.out.bam

In every instance I get the message: "WARNING: Multi-Hit not found". I pasted the beggining of the output of a run I did.

In this particular library, I got the warning 1997 times.

What is happening? Should I add a option to Cufflinks?

Did you ever figure out what was causing the error? I am also running cufflinks with RNA-seq alignments I did with Tophat and get the same error.

I ran cuuflinks without the '-u' option
