The docs suggest placing CFLOCK around CFX tags strictly for threading
issues. Many CFX tags are not thread safe internally (I think Forta's
CFX_Spell is the favorite tag to pick on here) and have the potential to
crash or hang your server if not properly locked. As a side note, our
company always locks CFX tags using the CFX_tagname as the lock name.
Assuming all apps on the server follow this same rule, this ensures that
it's locked and safe across multiple applications.
Locking CFML tags should not be needed. If your CFML tag uses application,
server, or session variables internally, I would suggest locking them within
the tag. You should always be looking to reduce the amount of locked
runtime to an absolute minimum.
