java - HSQLDB SQL异常 : Out of memory establishing database connection

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:

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

有人知道打开它并分析问题所在吗？

通常，当数据库损坏时会出现此异常。尝试备份数据库。参见 here有关此主题的另一次讨论。
