Done in SVNs #39995 & #39996 in Dev ....

A template will be now be skipped (not saved for future dissection) when there
are "too many" fields (specified by a CFLOW preference) or if a template with
the same "name" has already been seen.

Note that this means that a replacement template on a connection which
represents a change (i.e., is re-sent with different fields) will be ignored
and thus dissection of following data packets using that replacement template
will be incorrect.

I'm guessing that resending a template with different fields is not something
that normally happens. 

If needed, handling this case can be done as a future enhancement.



P.S. Thanks for the report !
