Gentle Greetings,

Has anyone noticed any situations where Admin sessions on the server get
hung and become "ghost" sessions that will not go away?  Cancelling has no
effect.  Opening a separate Admin session and cancelling from there has no
effect.  In some cases, subsequent sessions get hung and a reboot is
necessary.  And in other cases, there seems to be no adverse side effects.

In this case, I was doing some SQL queries on the database, and two user
Admin sessions hung and two Query Admin sessions hung.  (Fortunately,
everything else is continuing to run smoothly.)  Below is the output from
"show threads" related to these 4 sessions.

We are running 4.1.2 Server on an IBM M80 running AIX 4.3.3.

Thank you in advance for any help and/or suggestions.

Jennifer
