What Are the Most Common Solutions?
Before troubleshooting high utilization problems, make sure that you have
followed the steps in “Using a Troubleshooting Methodology” on page 105.
Check the Novell Support Connection Web site (http://support.novell.com)
for NetWare patches or updated NLM programs. Available patches will
contain fixes for reported high utilization problems related to the actual code
of the operating system and eDirectory.
However, a number of high utilization conditions can still result from
problems with configuration, levels of NLM programs, and tuning issues.
One of the first things you might want to do is discover the NLM program and
threads that are using the CPU. To do this, complete the following steps:
1 Access NetWare Remote Manager.
2 Click the Profile/Debug link in the navigation frame.
3 Click the Profile CPU Execution by NLM link.
4 Note the parent NLM program and threads that are taking the longest
execution time.
5 If possible, unload the offending NLM program to see if the problem
disappears.
You can also use the following list of issues to help you resolve problems.
The items in the list are categorized, but are otherwise in no particular order.
The list represents the collective experience of Novell Support
representatives. We recommend that you review each item, using each to
carefully analyze your system. Except for problems new to NetWare 6, you
will be able to resolve the problem on your own in almost every case.
