What's your updated IOS version?  I'd try 15.0(2)SG8 - you might be hitting this issue:

We had downgrade the software version 12.2(54) SG1, and had tested it.

maybe 10-12 s.

Thank you very much,Lulian!

But we feel very sorry.

As I said, I'd try 15.0(2)SG8 (released December 2013) - it's much more recent than 12.2(54)SG1 (February 2011) and it's supposed to have fixed that bug...
