I assume Basic History?
Does it output any event to [Workplace Structure]Web System Workplace:System Event List as it start / fail?
If it reaches "Ready" it should have been able to open all log files on disk. In "Ready" state Basic History is starting OPC subscriptions. Then, the problem is likely within data subscription.
Does the process crash (change PID)?
Then I strongly recommend filing a support case with your regional ABB support center. They will likely ask you to temporarily enable "Dump On Exception" to create a full memory dump of the process when it crashes. Dumps can be analyzed by R&D.
Otherwise, you could try disabling ALL logs (easy using Log Summary aspect, don't forget to hit the Save button once you've done Disable all) and see if the service reaches service state. If so, start enabling logs in smaller batches. With additional Log Summary aspects you can start per control network, per controller, etc. until you see the problem again. Likely, the last batch of logs you enabled contain some problem.
