Is that better or worse than before you changed log file size?

The bulk insert runs for three hours then crashes? Or multiple bulk inserts run and the Nth crashes? If the latter, what is N?

Mostly OLTP or OLAP in those periods? Is error log from such crashes significantlly different from bulk insert crashes?

From the error log ...

The smaller a transaction, the better. Let's see the SQL for such transactions.

While I look at the latest readouts ...

Why do you need the general log?

Why not move innodb_log_group_home_dir to another HD?
