HSQLDB SQLException:内存不足,建立数据库连接

Question

我们有一个带有本地HSQLDB数据库的桌面应用程序.一些客户报告他们的应用程序停止工作.当我尝试使用DbVisualizer打开它时,我可以在调试控制台上看到它:

12:45:32 [DEBUG pool-2-thread-1 D.?] RootConnection:     jdbcDriver.connect("jdbc:hsqldb:C:\test\database.db", {user=**, password=})
java.sql.SQLException: error in script file line: 56 out of memory

任何人都知道要做些什么来打开它并分析问题是什么？

通常,当数据库损坏时会发生此异常.尝试备份数据库.有关此主题的另一个讨论,请参见此处.
