Hi Santosh,
The only reference I could find to that illegal window scaling value error is from a single case where the escalation engineer suggested this was an issue with a host on the network not supporting RFC 1323 for window scaling.
I don't know what the actual issue is or whether an upgrade would improve LTM's handling of it. But the 5100 platform can run 9.3.x or 9.4.x. If you had support on the unit as of 2007-10-09 you could upgrade the unit to 9.3.1. For 9.4.8 you'd need to have had support for the unit on 2009-05-27. See SOL7717 for details:
