TRACE logs on 56-5.6.42-rel84.2.el6.x86_64 (possible due to tokudb?)

Description

We run several Percona Server instances. They were updated from 56-5.6.41-rel84.1.el6.x86_64 to 56-5.6.42-rel84.2.el6.x86_64 and immediately all servers that also have tokudb installed are flooding huge amounts (few GB/hour) of TRACE events to mysqld.log, example:

Otherwise the server configurations are very similar between servers that log TRACE and servers that do not; I suspect the main issue is the presence of:

Percona-Server-tokudb-56-5.6.42-rel84.2.el6.x86_64

Other components on servers without the issue:
Percona-Server-shared-56-5.6.42-rel84.2.el6.x86_64
Percona-Server-client-56-5.6.42-rel84.2.el6.x86_64
Percona-Server-server-56-5.6.42-rel84.2.el6.x86_64

 

Config files could be given in private if needed.

Sorry for the duplicate, I did a search for "TRACE" and found nothing relevant. Thanks for confirming. Is there a fix in roadmap?

Or since tokudb seems to be ~deprecated will it not be fixed?

Hello

Thank you for the report.

Cause for the extra TRACE in logs is 'Tokubackup'. Disable it will solve this problem. 

The issue already reported in .

Example:

 

after this, you will not see these TRACE in the error log.
