The information in this article applies to:

SYMPTOMS

Exchange Server 5.5 may not function properly on DEC Alpha EV6 (21264) computers. In particular, Exchange Server may stop responding (hang) or experience performance problems. Note that this problem does not occur on earlier DEC Alpha computers, including the EV4 (21064), EV5 (21164), and EV5.6 (21164A).


CAUSE

Certain operations performed by the Ese.dll dynamic-link library (DLL) file do not completely conform to the DEC Alpha architecture specification.
