---++How Can I configure parameters to avoid out of memory error?

In order to avoid out of memory error, you should make sure the values for the paramaters <b>NumberOfBuffers</b> 
and <b>MaxCheckpointRemap</b> are not set with the same values. 

For example, the following configuration will cause an error out of memory:
<verbatim>
# virtuoso.ini

...
[Parameters]
NumberOfBuffers = 246837
MaxDirtyBuffers = 18517
MaxCheckpointRemap = 246837
...
</verbatim>

Changing the value of the parameter <b>MaxCheckpointRemap</b> with let's say 1/4 of the DB size will resolve the issue.
