That is not easy to say. It is still a quite new product. A lot of tests have been written,
and the code coverage of these tests is very high. Randomized stress tests
are run regularly. But as this is a relatively new product, there are probably
some problems that have not yet been found.
some problems that have not yet been found (as with most software). Some features are known
to be dangerous by design, and some problems are hard to solve. Those are:
</p>
<ul>
<li>Using SET LOG 0 to disable the transaction log file.
</li><li>Using the transaction isolation level READ_UNCOMMITTED (LOCK_MODE 0) while at the same time using multiple
connections may result in inconsistent transactions.
</li></ul>
<p>
In addition to that, running out of memory should be avoided.
In some versions, OutOfMemory errors while using the database could corrupt a databases.
Not all such problems may be fixed.

- You can find out if the database is corrupted when running SCRIPT TO 'test.sql'
- What version H2 are you using?
- With which version of H2 was this database created? You can find it out using:
select * from information_schema.settings where name='info.BUILD_ID'
select * from information_schema.settings where name='CREATE_BUILD'
- Did you use multiple connections?
- The first workarounds is: append ;RECOVER=1 to the database URL.
Does it work when you do this?
