Thanks again, I should have tried this earlier

I've downgraded the firmware/bios to 1.46 and setup replication for 1024GB. The system past 2 initial replications, no crashes.

The release notes of Areca firmware/bios 1.47 state that there has been a modification to the SendAbortTask, maybe thats the issue?

I'll keep on testing and keep you updated on my progress.
If it is still working after a week I'll say the problem is fixed
