Bug: When querying with subfields where the OID is not in the subfield list returns Network I / O errors
** This issue is addressed in ArcSDE 9.0 Service Pack 3 (SP3) **
Intermitant "Network I/O" errors occur when querying with subfields where the OID is not in the subfield list. Usually this is encountered when using custom ArcObjects code that uses subfields in definition queries that do not include all fields (including the OID column).
