Re: [Wrapper-user] Windows page file increasing

[Todd W. <to...@sc...>]

Hi Leif,

Thanks so much for you willingness to help.  We're using method #2, and
are not calling any of the WrapperManager API calls.  I have no doubt
that we could still be doing something wrong, but thanks for helping to
troubleshoot.

The page file seems to increase as much as about 10 MB every few
minutes, so it can become a pretty big problem.

I can certainly describe to you how to reproduce the issue.  It's a bit
involved, so, if it's okay, I'll email you off the list about it.

Thanks much,

Todd
