Stack Overflow Web AS 640 SR1 ABAP

Hi,

After installing netweaver 2004 sr1 I unicode notice that my ABAP work processes would hang. Using SM50, I discovered that I am running into stack overflow problems. Has anyone encountered this on Windows 2003 server and MS SQL 2000 DB? I also noticed error RFCIO_ERROR_SYSERROR in abrfcio.c in rfc trace.

thanks.
