[rt-users] RT 3.8.8 upgrade stacked on database upgrade

Hi all,
I went through all the documentation that I've found to upgrade from 
3.8.8 to 4.2.11(from old server to a new one) so what I am doing is:
I am using SLES12, MariaDB 10.0.16

-Create DDBB for the rt04
MariaDB [(none)]> create database rt4;

-Load rt3 dump to the new DDBB named rt4
mysql -u root -p --default-character-set=binary rt4 < /srv/tmp/rt3.sql

-Create schema
perl etc/upgrade/upgrade-mysql-schema.pl rt4 rt_user rt_pass > queries.sql

-Load schema
mysql -u rt_user -p rt4 < queries.sql

-Make upgrade
make upgrade-database

And at this point the upgrade stops and drops an error (after filling up 
the disk). I've got a 10G database within a 100G hard drive,

Proceed [y/N]:y

The file that is taking up the space is:

#sql-ib162-2876089901.ibd nearly 80G

Those are the logs from /var/log/mysql/mysqld.log

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 
137034 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0x0 thread_stack 0x48000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

I would really appreciate any help on this.

Best regards.
