1667C44 16690C4 1669248 1B8D06C 1B83AF8 (switch_name)
Jan 23 11:03:43: %UTIL-3-TREE: Data structure error--attempt to remove an unthreaded node from a tree (switch_name)
-Traceback= 2A3F898 1441444 1441784 1442658 13EC0F8 13F6BC8 13F702C 13F8AF8 1667C44 16690C4 1669248 1B8D06C 1B83AF8 (switch_name)
this is the 3750 stack
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 52 WS-C3750-48P 12.2(53)SE2 C3750-IPBASEK9-M
2 52 WS-C3750-48P 12.2(53)SE2 C3750-IPBASEK9-M
* 3 52 WS-C3750-48P 12.2(53)SE2 C3750-IPBASEK9-M
4 52 WS-C3750-48P 12.2(53)SE2 C3750-IPBASEK9-M
it looks like this is following some problems to achive radius servers.
stack looks like stable now and no messages in log at the moment.

Generally, anytime you see a traceback, it's related to a bug. You might try updating your IOS to a later patch release, as something like SE2 would be early in the lifetime of an IOS.
You might also consider updating to a later IOS. The latest patch releases in train 12.2(55) appear to be very stable.

thankyou Joseph. i will try to update IOS to the latest release and see what happen.
I think this is the first time we had this problem, even if we have hundred of switch installed with many different IOS release and models.
I will try to search on logs for 'traceback' and see if something interesting come out.
will post if i'll find something interesting.
thank you
