HttpError "Session state has created a session id..."

[PL]

I've seen a few of these in the eventlog, what in the world would cause something like this,
why can't it save the session id cookie ??

Exception type: HttpException
Exception message: Session state has created a session id, but cannot save it because the response was already flushed by the
application.

System.Web.SessionState.SessionIDManager.SaveSessionID(HttpContext context, String id, Boolean& redirected, Boolean& cookieAdded)
at System.Web.SessionState.SessionStateModule.CreateSessionId()
at System.Web.SessionState.SessionStateModule.DelayedGetSessionId()
at System.Web.SessionState.SessionStateModule.OnReleaseState(Object source, EventArgs eventArgs)

at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

PL.

Never had this one. My guess would be defining a session variable after
having flushed the response buffer. Try perhaps a sequence such
Response.Write, Response.Flush, Session("Test")="A".

Let' us know...

But this happens on a page where I don't use any session variables at all,
it seems it happen on the very first request and only intermittently.

Seems like a bug to me, if someone from MS could give any insight that would be nice.
