Enabling loadAllMembers options running on 32-bits PHP when the bot is at least in one of guild considered "large" will crash after chunking up the members:

Stable v6.0.3 is also affected.

Might be related to the ratchetphp library.

Fixed by ratchetphp/RFC6455#65

Note: the fix only increased payload limit from 65 KB to 2 GB. Don't expect a 32-bits php can store all members in a very large guild with thousands of members going over 2 GB, that crash would simply mean you need more RAM and 64-bits php to cover it.

Since the PR is now merged (not released yet), you can temporarily apply the patch by:
composer require ratchet/rfc6455:"dev-master#82760a7 as 0.3.1

We'll add the patched version to requirements ASAP once it's released.
