## Cause

CloudGuard Controller for VMware NSX-T introduces a new feature, enabling the automatic scanning of NSX-T IP ranges within Network Groups.

This feature can cause CPU & RAM usage issues when used in environments with many IP addresses in IP ranges.

The feature is enabled by default on the following releases:

- R81.10 Jumbo HF Take 110 - Take 128
- R81.20 GA - R81.20 Jumbo HF Take 38

The feature does not exist on:

- R81.10 GA - R81.10 Jumbo HF Take 94
- R81.10 Jumbo HF Take 130 and above

## Solution

Upgrade to one of the following Jumbo HF takes or newer. On these takes, the feature is disabled by default:

- R81.10 Jumbo HF Take 130 and above
- R81.20 GA - R81.20 Jumbo HF Take 41 and above
