Overview

You are experiencing high CPU utilization on the Exinda 3062. The tcpad process is consuming high CPU. TCP health in the WebUI have large numbers ignored and refused connection for Internal and External hosts. Also, the total internal and external connections are exceeding 150,000. 

Solution

• Execute the following command in CLI to address the high number of ignored and refused connections for Internal and External hosts:

ddos tcp ignore

• To address the high number of connections, check whether the WAN memory partition is close to full under System > Setup > Storage. If yes, clear the acceleration caches by going to System > Optimization > Wan Memory and choose
  • Force Data Expiration (this takes some time to complete)
  • Reset the Persistent Data (restarting WAN memory will be quicker)
• Login to Exinda WebUI and navigate to Configuration > System > Diagnostics > Diagnostics and click on 'Generate Diagnostics' to generate a new diagnostic dump.
• Generate scheduled reports for the past 7 days..
  1. Go to Monitor > Scheduled reports.
  2. Add a new report with all the options selected for the report frequency.
  3. After adding, click on the Adobe icon to download the PDF report.
  4. Wait on the same page until the report is generated.
  5. Due to the high CPU utilization, network monitoring reports may take more time than usual. Try generating the reports during off-peak hours when there is less load on the Exinda
• Check whether the 3062 model supports the total number of connections. If so, it is recommended to purchase a hardware device that is capable of processing more connections and handles acceleration in a better way, such as Exinda 4062 or 8063 series. You can contact GFI Sales for available hardware options and device upgrades. The Exinda products related information can be found under The Exinda product line documentation.
