I did that already earlier when I reported about similar issue, which
made K totally unresponsive for a long period of time. Nothing was
found from the backtrace.
What you can also try, is to change the database table
type. What do you
have now, MyISAM, InnoDB or something else?
DB type is InnoDB.
To know better the ecosystem, what is the operation
system and
mysq/mariadb versions?
Latest stable Debian 10 that comes with mariadb 10.3.
On the positive side, so far the issue has not appeared after I
backported your db_cluster async insert patch to 5.3. Perhaps there was
some issue in falling back to normal insert.
