Hello,

that's pretty strange, since several customers (and we, too) are using both components in our websites.
Are you 100% sure that this always happens when Admin Tools is published? Can you please try to run 2-3 backups with Admin Tools enabled and see if you always get the error?
If you always get the error I suspect your site has very few available resources and when Admin Tools tries to inspect the request, you exhaust them and the host closes the connection.
Let me know how it goes with your tests, I think I may have a workaround for you.

Akeeba Backup process takes an huge amount of resources, and sends a very small form on every request.
It's very unlikely that Admin Tools will take more than a backup process to process a request with very few data.
If your backup process fails it's because is using too many resources and your host doesn't allow it: Admin Tools will add just a cup of water in an ocean of CPU usage ;)

Please try to use the following settings:
Minimum execution time: 5 seconds
Maximum execution time: 1 second
Runtime bias: 50%

Yes, minimum is greater than maximum, that's not a typo. This will slow down the whole backup process but it should not fail.
