Hi all, I am still seeing this issue on the latest G-Reg pack downloaded from [1]. This may not be harmful for the functionality but it sure slows down the server. For instance, when I do a metadata search, it takes a conciderable amount of time to return the search results since the 'Null LdapSession warning' is being printed continuously. Appreciate if somebody could look into this issue.
