Environment

Novell Open Enterprise Server 2 (OES 2)

Situation

When using iManager and going to "Cluster Options" you see a 503 error "server not available" after several minutes of waiting.
All of the other cluster links in iManager work.

Resolution

The "Cluster Options" link is doing a non cluster specific query to eDirectory for each cluster resource.  This would return all objects under the ldap context.  It would do this search one time for each resource, so if you had 20 resources it would do the search 20 times and return a large amount of data each time.  In effect the search would take longer to complete than the timeout and you will see the 503 error.
This is fixed in an updated /opt/novell/ncs/bin/clstrlib.py file that now only searches for cluster specific information thus returning a much smaller data set and speeding up the entire process.
