Made an error with severity.

data node trace and out log files are probably needed to diagnose this, also: does this happen on a fresh cluster start, or on a cluster that is already populated with data?

This happens on one of the data nodes. It has data in it already.

Assertion failure happens in this function: /* -------------------------------------------------------------------------- * IT IS NOW TIME TO FIND WHERE TO START EXECUTING THE LOG. * THIS SIGNAL IS SENT FOR EACH LOG PART AND STARTS THE EXECUTION * OF THE LOG FOR THIS PART. *-------------------------------------------------------------------------- */ void Dblqh::srLogLimits(Signal* signal) on this assertion check: 18157 if (logPartPtr.p->lastLogfile == logFilePtr.i) { 18158 * ndbrequire(logPartPtr.p->lastMbyte != tmbyte); 18159 }//if Not sure what this is exactly checking for, but it looks as if "the log" (Redo log?) is corrupted, and there is probably now way around this that would fix the situation besides setting up the cluster from scratch and restoring the most recent backup ...?

I have reinitized the data node and seemed to run for a while. It has now crashed again after 10 days. Seems to be a different bug. Reported it as bug number 69822.

We have seen a similar crash in our test runs occasionally, but it happens extremely seldom, so has still eluded us.
