Problem: ArcSDE 8.1.x giomgr process core dumps on AIX 4.3.3
The ArcSDE giomgr process core dumps on AIX 4.3.3. This prevents further connections to the ArcSDE application server until the application server is restarted. To restart the ArcSDE server, all currently connected users have to disconnect.
The problem has been identified to be caused by the AIX operating system mutex handling and occurs when a number of users simultaneously disconnect from the ArcSDE server.
Solution or Workaround
Install AIX OS Patch IY23453. See Related Information for the IBM technical support Web site.
