Description:
Hello,

we have a mysql cluster with 2 MySQL frontend server and 2 MySQL datanode server.
Because of many problems with one datanode we stopped one datanode.

Now we have two times this problem on the other (running) datanode:

2007-01-08 18:35:37 [ndbd] INFO     -- Configuration fetched at mysql1 port 1186
2007-01-08 18:35:38 [ndbd] INFO     -- Start initiated (version 5.0.27)
2007-01-09 13:32:33 [ndbd] INFO     -- Error handler shutting down system
2007-01-09 13:32:34 [ndbd] INFO     -- Error handler shutdown completed - exiting
2007-01-09 13:32:34 [ndbd] ALERT    -- Node 3: Forced node shutdown completed. Initiated by signal 0. Caused by error 2341: 'Internal program error (failed dbrequire)(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node'.

Then we must start the datanode manually again.

How to repeat:
Dont know, because we have a few developer that working on the cluster.

Hi,

these tracefiles look really "interesting",
is this in any way reproducable?

I still investigating in this issue.
Unfortunately nobody can help me.
Do you have any clue from the trace files?
All help is appreciated.

Hi,

It looks like it's somthing related to auto-increment.
Maybe it helps....

/Jonas

jonas notes:
It looks like a really rare combination of TUPKEY_REF and LCP start.
The table used is 0 -> using auto-increment.
