too many constraints in database

Item Value
SQLCODE -936
Constant SQLE_TOO_MANY_CONSTRAINTS
SQLSTATE 54W02
Sybase error code 13551
ODBC 2 State ERROR
ODBC 3 State ERROR

Probable cause 

An attempt to create a new constraint failed because the SYSCONSTRAINT table is full. If the SYSCONSTRAINT table has a number of unused slots, then reloading the database will reclaim unused space.
