Description:
I meet this bug:

Current byte-offset of file-pointer is: 1067

Time: Friday 18 October 2024 - 13:02:15
Status: Temporary error, restart node
Message: Send signal error (Internal error, programming error or missing error message, please report a bug)
Error: 2339
Error data: Signal (GSN: 12, Length: 1, Rec Block No: 0)
Error object: /home/mysql-cluster-gpl-8.0.40/storage/ndb/src/kernel/vm/SimulatedBlock.cpp:809
Program: ndbd
Pid: 109465
Version: mysql-8.0.40 ndb-8.0.40
Trace file name: ndb_2_trace.log.1
Trace file path: /usr/local/mysql-cluster/data/ndb_2_trace.log.1 [t1..t1]
***EOM***

How to repeat:
I don't know, I stumbled upon it by accident, and the whole thing crashed when I found it, I'll upload the trace.log later.

Suggested fix:
I have no idea. All I know is that it causes crashes, maybe something in fault tolerance?

I cannot reproduce this unfortunately, without knowing how to reproduce this here's not much we can do, especially as you did not run this on latest version of ndbcluster.
