How to repeat:
- try to import a big table (10 Mio. rows, disk data table) with mysqlimport
- try "alter table add index" operations on big tables (10 Mio. rows, disk data table)

Can you measure the memory used by the involved processes? Maybe it's an out-of-memory error or a resource limitation. Just a tip can be tested quickly.

Hello,

this bug is the same as my new bug report described in Bug#34107.

So this thread can  be closed.
