Hi,
      We have been using H2 databases in our production, recently due to 
one activity somewhat like 800000 records were inserted to a table in that. 
And as a result the database got corrupted. As far as we know, it is a bug 
in H2 database that it can get corrupted any time. So, it is just heads up 
to the team about the recent issue regarding this which we are facing 
currently. Please revert back with the suggestion about anything that we 
need to do to get out of this situation.

This is the error we are getting,

General error: "java.lang.ArrayIndexOutOfBoundsException: 793" [50000-174]
