Question

每当我在我的数据库上调用SHUTDOWN DEFRAG时，我最终都会收到错误（我认为IllegalStateException）它无法找到特定的块！

我已经尝试了多次，并且总是得到与缺少块相同的结果。数据库很大（100+ GB）。我从我拥有的大约4GB的数据库开始，然后在它增长到100+ GB之后，防止数据库失败。这发生了几次。在我开始扩展数据库的程序之前，我甚至尝试了恢复工具并重新创建了4GB数据库，然后在该数据库上运行SHUTDOWN DEFRAG并且它工作正常 - 但是在数据库增长到100多GB之后又一次SHUTDOWN DEFRAG因为无法找到大块而停止工作。

任何人都会看到这样的事情，或者有人知道可能出现什么问题？

我正在使用：Windows 2012 R2 (64 bit)，Java 8 (1.8.0_102-b14)和H2 (1.4.191)
