for some customers we have a self-created webservice/API which connects to the Act! framework (because at that time the Web API wasn't available yet or did not meet the requirements).
At some random moments, the ActFramework.Logon gives this exception:
System.ArgumentException an item with the same key has already been added. (SupplementalFileManager)
Also, since one of our customers moved to V21 (and we built a v21 version of the API) the login process is -sometimes- very slow (over one minute).
How can we solve these things?
