The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Backup Data Transfer causes NIC messages?

Asked by e_sandrs in Linux Administration, Backup & Restore Software, Network Cards & Adapters

Tags: 0, suse

We're getting pretty much a "continuous flood" of the informational message below on a SUSE OpenLinux box running the CA BrightStor ArcServe 11.5 SP3 client and communicating with a Windows box running the full version of ArcServe (same version and patch level).

Anyone have any ideas on how to diagnose or fix this?  More info as requested...
-----------------------
The following is only an harmless informational message.
Unless you get a _continuous_flood_ of these messages it means
everything is working fine. Allocations from irqs cannot be
perfectly reliable and the kernel is designed to handle that.
