Description of problem:
Configuring the feature 'Alternate Content Source' (ACS) to use the Capsule gets 'Out of memory' errors.

Version-Release number of selected component (if applicable):
Satellite 6.13.1

How reproducible:
Create an ACS to sync the product 'Red Hat Enterprise Linux for x86_64'

Steps to Reproduce:
0. Have RHEL9 BaseOs+AppStream repos synced and promoted in LE in some CV, and sync that LE to a Capsule
1. Create ACS via Satellite WebUI:
2. Content
3. Alternate Content Sources
4. Click over the button 'Add Source'
5. Select the option 'Simplified' -> Next
6. Type:
Name: RHEL 9
Description: RHEL 9
-> Next
7. Select one capsule -> Next
8. Select the products: Red Hat Enterprise Linux for x86_64 -> Next
9. Click over the button 'Add'
10. Click over the button 'Refresh source'

Actual results:
The server is not able to refresh the ACS, getting the 'Out of memory' errors

Expected results:
The server is able to refresh the ACS using the current resources without errors

Additional info:
It seems the 0. step is a must; the content from the ACS must be synced to the Capsule already..?
