Hi, Running radiusd 2.0pre2 (cvs head) Just checked the system logs on one of our radius servers, and i'm seeing some strange error messages from directory services. Oct 12 12:02:50 wolverine DirectoryService[54]: Potential VM growth in DirectoryService since client PID: 9179, has 675 open references when the warning limit is 500.

Oct 12 13:59:09 wolverine DirectoryService[54]: Potential VM growth in DirectoryService since client PID: 9179, has 875 open references when the warning limit is 500. PID 9179 is radiusd. So it would seem that radiusd has an ever increasing number of references (though I have no idea what it means in this context), against the DirectoryServices Deamon. With API debugging on I see Oct 12 14:15:28 wolverine DirectoryService[54]: Client PID: 9179, has 896 open references.

Could this explain the possible memory leak in radiusd, that only seems to appear on Darwin ? -- Arran Cudbard-Bell (A.Cudbard-Bell@sussex.ac.uk) Authentication, Authorisation and Accounting Officer Infrastructure Services | ENG1 E1-1-08 University Of Sussex, Brighton EXT:01273 873900 | INT: 3900
