Hi there, I'm using freeRADIUS 1.1.6 and am authenticating users via NTLM to AD. From time to time, radiusd stops authenticating connections and I see in radius.log that the maximum number of threads has been reached: Fri Jun 8 13:55:54 2007 : Info: The maximum number of threads (32) are active, cannot spawn new thread to handle request Fri Jun 8 13:55:59 2007 : Error: Discarding duplicate request from client nm5406-10:1025 - ID: 229 due to unfinished request 214 Fri Jun 8 13:56:04 2007 : Error: Discarding duplicate request from client nm5406-10:1025 - ID: 229 due to unfinished request 214 Fri Jun 8 13:56:04 2007 : Error: WARNING: Unresponsive child (id 2786053008) for request 213 Fri Jun 8 13:56:09 2007 : Error: Discarding duplicate request from client nm5406-10:1025 - ID: 229 due to unfinished request 214 Fri Jun 8 13:56:16 2007 : Info: The maximum number of threads (32) are active, cannot spawn new thread to handle request Fri Jun 8 13:56:21 2007 : Error: Discarding duplicate request from client nm5406-10:1025 - ID: 230 due to unfinished request 215 Fri Jun 8 13:56:26 2007 : Error: Discarding duplicate request from client nm5406-10:1025 - ID: 230 due to unfinished request 215 Most of what I have been able to gather seems to indicate that this is because of a 'slow' server. I seem to be hitting this even with a very quiet test environment, and only a handful of supplicants. I can't reproduce this at will, and would appreciate any suggestions to correct.
