Java iView Runtime error while login

Question

Hi,
We are facing with a problem while logging on to the SAP Portal 7.0. We are not just facing with this problem on Portal logon, the other J2EE applications also, such as useradmin. The problem arises as soon as we logon to the Portal. Please find the error that we see, in the defaultTrace.trc;
#1.#000C76B60849007F0000003E0000137800045453E43B925E#1218619194843#com.sap.engine.services.security.authentication.programmatic#sap.com/irj#com.sap.engine.services.security.authentication.programmatic.logon####n/a##fdc17ab0691811dda2c9000c76b60849#SAPEngine_Application_Thread[impl:3]

We are getting this same error when logging into our portal - on NW 7.0 Enhancement Pack 2.  We don't get it all the time.  Most of the time login is very quick.  But sometimes, the login hangs for 5 minutes before letting someone in -
with nothing being output to the default trace file.  But sometimes, the user is refused and the following stack trace appears.

The user then tries again and can get in.  When one person is hanging, we are all hanging for a while.  Then everyone clears up at once.  I don't know if that error is related to the hang, but since I found this thread, I thought I'd ask
if it ever got resolved.  The last post to this thread discussed a property, but ours is set correctly when seen in the Visual Administrator.
We do use Single Sign On for most users, but this behaviour is happening when we set Negotiate=false and login with our username and password or when doing SSO, so I don't think it is related to that.
