fluent mesh importing problem
 

I am having a problem importing a mesh created in gambit to fluent. Fluent seperates one of the interior zones multiple times then the error:

Note: seperating interior zone 91 into zones 91 and 103

default-interior -> default-interior(91) and default-interior:103 (103)WARNING: no face with given nodes. Thread 11, cell 786

Can anyone tell me what this means? and what the likely causes of it are? Thanks in advance
