Subject OutOfMemoryException when executing 180,000 batches
Date Tue, 08 Nov 2011 22:44:12 GMT
Is it unusual that Derby (used in-memory only) seems to throw an out of memory exception when
executing 180,000 batched insert statements?
(The JVM was started with -Xms1024m -Xmx2048m):

Caused by: java.sql.SQLException: Java exception: 'GC overhead limit exceeded: java.lang.OutOfMemoryError'.

Are there memory limitations for Derby running in the in-memory only mode?
Is there anything that can be done to avoid getting such errors?
