It does seem related to http://bugs.mysql.com/bug.php?id=18298 ... there are some ordered unique indexes in the database. While I usually experience the problem after only 4 to 6 kills, my most recent test did not experience it until after 8 kills. During that test, there was no database activity.

Hi, I checked log, am currently 99% sure that this is it. If you want to be 100% sure you can run >ndb_show_tables locate table 3 in output and verify that it is an index. (using the exact same cluster as the one that crashed...) I'm closing this as duplicate, please reopen if you disagree. /Jonas

Table 3 is indeed an index: 3 OrderedIndex Online No c4_ddawe_ndb def PRIMARY Thanks.
