HI,

>>
i thought that it was something like that but i cannot figure out why it varies in size so greatly from 5/6 mb to 27 or so in the matter of a few clicks of the mouse, i don't use large datasets or large dlls so i can't see why it need this much memory

Does the DLLHOST memory consumption increase indefinitely or peak at around 27MB? Is it triggered by a call to a specific DLL ? How do the DLL's behave outside IIS (is it IIS - you didn't say?)

Regards,
Viv
