Description

i am trying to insert values into the database table EVENTS_TABLE where i have 18 columns with EVENT_ID as Unique but can be null. Indexes for this table is EVENT_INDEX which points to EVENT_ID internally. Now at some point of insertion into this Table, i am getting "The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'EVENT_INDEX' defined on 'EVENTS_TABLE'." error in my logs and in derby logs i am getting ERROR XSDBB: Unknown page format at page Page(1936,Container(0, 1009)), page dump follows: Hex dump: 00000000: error.

Please let me know why this is happening and what is the meaning of this error.
