Ina,

I tried to go through the LDP RFC to see if it specifically says that a 
wildcard
release message should be sent only in response to a wildcard withdraw 
message.

There may be a timing condition in which an upstream router may still hold
a label for which downstream router has removed it from the incoming label
database.

draft-ietf-pwe3-control-protocol-08.txt probably talks about a similar 
situation for
wildcard release for L2 FECs as below

"A wildcard  release message MUST include only the group ID. A Label Release
    message initiated from the imposition router must always include the 
   PW ID."

Any thoughts?

Regards,

Rama Ramakrishnan
