SQL Server : A system assertion check has failed...

SQL Server : A system assertion check has failed
                                                                    Last Week we have to face SQL Server error. while executing SQL Server(T/SQL) script(Script contains SQL Server Cursor with Update). It's really confuse me after restart(physical server restart not SQL server service) database server (luckily this error occur in our development database environment) it's fine, but again it's coming.

Full Error and details as follows,

Location:     pageref.cpp:1340


Expression:   0 == pageFull


SPID:         55


Process ID:   1041


Msg 3624, Level 20, State 1, Line 60


A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.


Msg 0, Level 20, State 0, Line 0


A severe error occurred on the current command.  The results, if any, should be discarded.

After execute CHECKDB it wont display any errors. 


DBCC CHECKDB WITH NO_INFOMSGS;
GO

 And I have found SQL Server Hotfix related about this error. And Microsoft mention cause of this error is "The issue occurs because the length of the key data is bigger than the length of the compressed key value buffer."
