[PATCH] OQGraph crash caused by SELECT queries

    XMLWordPrintable

    Details

    • Sprint:
      10.0.24, 10.0.25

      Description

      I deployed MariaDB 10.0.19 on our servers and encountered a crash that seems to happen irregularly after SELECT queries on an OQGraph table. It was reproducably happening on two servers, both running CentOS 7 (in a master-slave setup). I have so far been unable to reproduce the crash on any other system or even CentOS 7 inside a VM. I since was forced to revert those servers back to 5.5, but I would appreciate any pointers on how I could reproduce the crash I got.
