Hi sergey, i'm loggins querirss now to check when the crash occur
I think it's not related with create/drop, vit since i don't have the log i
cant provide some kind of 100% information just the log
You can create the bug eithout problemns
It's mariadb 10.1.5 glibc>2.14
The serve load was low i was testing only, near to 5 active connections,
others was connections not running anything just connections waiting queries
