Hi, This looks like a corrupt database. To recover the data, use the tool org.h2.tools.Recover to create the SQL script file, and then re-create the database using this script. Does it work when you do this?
With version 1.3.162 and older: on out of disk space, the database can get corrupt sometimes, if later write operations succeed. The same problem happens on other kinds of I/O exceptions (where one or some of the writes fail, but subsequent writes succeed). Now the file is closed on the first unsuccessful write operation, so that later requests fail consistently. Important corruption problems were fixed in version 1.2.135 and version 1.2.140 (see the change log). Known causes for corrupt databases are: if the database was created or used with a version older than 1.2.135, and the process was killed while the database was closing or writing a checkpoint. Using the transaction isolation level READ_UNCOMMITTED (LOCK_MODE 0) while at the same time using multiple connections. Disabling database file protection using (setting FILE_LOCK to NO in the database URL). Some other areas that are not fully tested are: Platforms other than Windows XP, Linux, Mac OS X, or JVMs other than Sun 1.5 or 1.6; the feature MULTI_THREADED; the features AUTO_SERVER and AUTO_RECONNECT; the file locking method 'Serialized'. So I suggest to upgrade to a more recent version of H2.
