2. Click the Configuration tab for the Server host.

3. Click Advanced Settings.

4. Click VMkernel.

5. Find the corresponding value field for VMkernel.Boot.netPktHeapMaxSize, and enter 128.

6. Find the corresponding value field for VMkernel.Boot.netPktHeapMinSize, and enter 32.

7. Click OK to save the changes.

8. Reboot the system.
