Error 1203



Message text

Caller of lock manager is incorrectly trying to unlock an unlocked object. spid=%d locktype=%d dbid=%d object id or page number=%ld.


Before the Lock Manager tries to unlock an object, it verifies that the object is locked. When an object is not locked during this check, error 1203 occurs.

This error is usually due to an Adaptive Server problem that causes an incorrect session descriptor pointer or logical page number to be passed to the Lock Manager.

Error 1203 can occur during an insert, update, or select, particularly on a table with an index.
