Environment
Novell NetWare 6.5 Support Pack 6
Secure Login Secret Store
Situation
Memory in both the VM and File System pools would become severely
fragmented eventually resulting in cache memory allocation failures
on the server console. Seg.nlm showed that the largest segment size
in both pools was less than 2mg. The server had about 4 gig of
memory installed. This server was using Secret Store to do secure
logins. There were thousands of workstations hooked up to this
server with many users as well.
Resolution
Ther is a setting for changing
the cache refresh interval (in minutes)" which was set for 5
minutes. (Imanager\-- SecureLogin SSO\Manage SecureLogin SSO\--
Advanced Settings). This should be set to 6-8 hours for most
environments. This setting dictates how often the local cache
on the workstation should check in with eDir for changes/and
updates. With that many workstations checking the ds cache on the
server every 5 minutes caused the problem. After setting this to 8
hours, the problem was alleviated.
