Hi,

No variables to tweak the tokudb memory allocation ?
By default tokudb_cache_size takes half of the total system memory.
With 6G allocated to InnoDB buffer pool, and 1G to the MyISAM key buffer, are you sure you have enough memory for TokuDB ?

You might try to find the source of the termination with this:

Hello,

I've been a proudly user of mariadb 5.5.x for a long time now  but given the nice feature setI decided to give mariadb 10.x a try.

I took one of our current slaves running mariadb 5.5.x (on centos 6.5) and followed the upgrade steps using yum and ran *mysql_upgrade*. The upgrade ran without any trouble...then I moved a huge table (about 1B records right now) from InnoDB to TokuDB. 

Now, every couple of hours I find that the replication is far behind the master and the reason is because this server keeps checking tables marked as crashed....

I can't seems to find any indicator of OOM killer in the system logs NOR anything related to that in the mysql log, the only clue I have is:

---------------

The odd thing is that the 5.5.x version was working just fine (since about a year) in the same hardware...nothing changed in that front.

Any clue?

Thank you in advance
