We recently upgraded to Mercury 4.72 and Windows 2008 R2 on 32 bit architecture.
Occasionally , under high volumes our Mercury mail Queue is failing to process correctly. The Mercury service seems to be CPU bound, consuming 12%CPU on a Quad CPU for hours. No email is delivered. A restart of the service un-hangs it and the queue is quickly processed.
The log files show no errors.
We operate Mercury mostly as an internal SMTP relay engine to push PDF docs through a larger Exchange PostOffice.
Below is our INI file. Any suggestions are greatly appreciated.

# MERCURY.INI generated by Mercury Setup

#
# Sample Bindery Mode MERCURY.INI file (in fact, the one I use on
# my production server). This one implements most of the possible
# switches for each module, but you can edit it to do less if you
# wish. All the fields shown below are described in the file
# MGUIDE.HLP which is supplied in the Mercury archive.
#
# Anything after a '#' to the end of the line is a comment and
# is stripped out before parsing. Trailing and leading whitespace
# is also stripped before parsing. Many sample commands have been
# left in this file commented out for reference purposes.
