Work Arounds for "The total number of locks exceeds the lock table size" (1 reply)

I have a table using InnoDB that has just over 11M rows. Constant inserts.

insert TabB select A from TabA limit 1 offset 7000000;

gives [Err] 1206 - The total number of locks exceeds the lock table size

insert TabB select A from TabA limit 1 offset 5000000;

works

select A from TabA limit 1 offset 7000000;

works

Changing the innodb_buffer_pool_size isn't viable at this time. What can I do?
