you can turn off all of the new logging (likely to be what your talking about) by adding an off line for every log category. See the wiki for details:
http://www.eqemulator.net/wiki/wikka...a=ServerLogSys
you'll basically have one WORLD=off, SPELLS=off, etc... line for each category in logtypes.h
edit: further, you can define the macro DISABLE_LOGSYS in the build if you want.
I see an issue with windows logging too much as well, will get it fixed.
