KIlling thread on Galera could cause mutex deadlock

    XMLWordPrintable

    Details

      Description

      There following issues here:

      • Whenever Galera BF (brute force) transaction decides to abort conflicting transaction it will kill that thread using thd::awake()
      • User KILL [QUERY|CONNECTION] ... for a thread it will also call thd::awake()
        Whenever one of these actions is executed we will hold number of InnoDB internal mutexes and thd mutexes.
        Sometimes these mutexes are taken in different order causing mutex deadlock.
