ERROR Shibboleth.ISAPI

[Ryan Larson]

Good afternoon, I am trying to clean up some noise in my shib logs where I
get the following in the Native Log:

INFO Shibboleth.SessionInitiator.SAML2 [2712] isapi_shib: postData property
not supplied, form data will not be preserved across SSO

Doing a bit of looking around I needed to add postData="ss:mem"
postTemplate="postTemplate.html" to my Sessions line in shibboleth2.xml.
When I add them I get the following error generated like clockwork every 24
seconds then 5 seconds then 24 seconds etc.  It does remove the original
INFO notification but places the following error in both Native and
Native_Warn:

ERROR Shibboleth.ISAPI [2712] isapi_shib: The request's Content-Length is
not available to an ISAPI filter.

This is being run on a Windows 2016 Box using IIS 10.  Shib Version is old
at 2.6.1.4.

Any thoughts on this?

Thanks!
