SYMPTOMS
A complex UPDATE statement that uses an Index Spool
operation in the execution plan may cause an assertion. This assertion causes the connection that is running the
update to be closed, but it does not affect the other connections to the server. A message that is similar to the following message is logged in the SQL Server error log:
2003-04-20 23:09:38.80 kernel SQL Server
Assertion: File: <scanrid.cpp>, line=315 Failed Assertion = 'm_len != 0'.
2003-04-20 23:09:38.81 spid7 Error: 3624, Severity: 20, State: 1.
