Hi, I am building a H2DB of about 10GB size and frequently (let's say about 10% of the time) get the following internal exception:
org.h2.jdbc.JdbcSQLException: General error: "java.util.ConcurrentModificationException: undoLog [1.4.180/0]"; SQL statement: COMMIT [50000-180] This does not seem to be dependent on the data, as it does not happen always, even though input data and build script stay the same. The process to build the database takes a lot of time and the exception seems to occur only at the COMMIT after the biggest INSERT (of about 2.5 million records, which takes about an hour to complete). It says "ConcurrentModificationException", but the database is only opened by one process, and it does not use multiple threads (at least not any that I created, I am just doing INSERT after INSERT). Can I give you more details somehow? How can I read the trace file that gets created? Thilo -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
