"01020066:3: The requested Node (/Common/fqdn1) already exists in partition Common."

Hello, when trying to POST a new application in a tenant that uses an already shared FQDN across tenants in the same cluster, the AS3 POST response is:

 

"01020066:3: The requested Node (/Common/fqdn1) already exists in partition Common."

 

It is saying that fqdn1 already exists in /Common, which is true, as it can be seen in other pools as a member.

 

Now, if I try a different FQDN (fqdn2), it works fine with no issues.

 

Any suggestions on how to find the root cause and fix this without:

 

deleting fqdn1 from everywhere, and

redeploying it?

 

 

Thank you
