REDO log files overloaded (no replies)

Hi guys,

we have a problem with our MYSQL Cluster configuration.
Mysql version is 7.1.10 (64bit) and I'm running a JBoss application server (version 5.1.0.GA).

Here is our first try setting the parameters in the config.ini file:

FragmentLogFileSize=256
NoOfFragemntLogFiles=380
RedoBuffer=256

We also created a tablespace for the data intensive table(s).

With the configuration above everything works fine for about 5 hours - than the following Error occurs "NDB error code 1234: REDO log files overloaded (increase disk hardware)".
When we run the system the same way but without the tablespace, no REDO overloaded error occurs but the "table ... is full" after about 8 hours.

When we change the configuration at the mentioned parameters, the system work less than 5 hours and we get the error "NDB error code 1234: REDO log files overloaded (increase disk hardware)" again.

Are there any suggestions what we can do?

Thanx,
Georg
