Summary0002412: `uu-world-scan` larger than `tiny` triggers watchdog, crashes server
DescriptionWhen performing a uu-world-scan with any setting larger than "tiny" (i.e. small, medium or large), the server crashes 60 seconds after starting due to a watchdog timeout. A tiny scan completes on my machine within 45 seconds, and thus does not trigger the watchdog timeout.

A UU world scan is basically required because I have a few mod items that are not included in the predefined IC2 UU configuration, most importantly AE2's certus quartz.
Steps To Reproduce1. Start the server
2. Connect as OP and enter the command: /ic2 uu-world-scan small
3. Wait 60 seconds
4. Server crashed (log below, crash report attached)
Additional InformationMinecraft 1.12.2
Forge 14.23.4.2705
IC2 2.8.94-ex112
For additional mods, see attached crash report file.

Server log, starting at the point where I entered the command via ingame chat:
