DB Node crashes

[Yannis Tsakiris]

Hello,
I have set up a NDB cluster consisting of two computers, with 2 MGM nodes, 2 DB nodes, and 2 API nodes (2 Replicas, 1 node group). I have used the last release of 4.1.5 (gamma-nightly-20040912). Here is the problem:
I start all the nodes of the cluster and everything seems to work fine.
Then I reboot the first computer, to check if the cluster will still working.
This causes the ndbd on the second computer to crash.
This is the last message of the db node's error log at the time of the crash:
Date/Time: Monday 13 September 2004 - 13:20:38
Type of error: error
Message: Arbitrator shutdown
Fault ID: 2305
Problem data: Arbitrator decided to shutdown this node
Object of reference: QMGR (Line: 3774) 0x0000000a
ProgramName: NDB Kernel
ProcessID: 2131
TraceFile: ./ndb_3_trace.log.17
***EOM***
I can't find an explanation why this is happening? Any ideas?
The config.ini file I use is as follows:
