Has any one seen where a user logs off and their sessions still shows up in onstat with no information and these will accumulate. After a while, and it varies on the count, but users will start getting errors stating they cannot login. This is happening on a AIX 5.3 ML5 box with IDS 9.40.FC6 John A.

This usually happens with Windows clients which do not properly shupdown the TCP connections. It is seen most often with BSD based UNIX servers (like AIX) where the network timeout detection is set too high (BSD default was over an hour). Reducing the network timeout detection to 15 mins or less alleviates the problem (don't remember the setting/kernel parameter). Art S.
