BUG #: 54745 (SQLBUG_70)



SYMPTOMS
A client connecting to the server using the multiprotocol network library, while the server is under memory pressure, may encounter a handled Access Violation (AV).

As an indicator of memory pressure on SQL Server, you may see error 17803 in the ERRORLOG:

Error: 17803, Severity: 17, State: 14

Insufficient memory available..

Error: 17803, Severity: 17, State: 17

Insufficient memory available..

Increase the amount of memory for SQL Server or reduce memory consumption of other applications on the server. You may also connect with another network library to avoid the problem.
