Hi all,
Why the checkpoint take longer time to complete? Is it something not right

OS = Sun Solaris 2.6

Any help would be greatly appreciated. Thank you.
Best Regards,
Jason

Jason , This is only a text group. PLEASE , PLEASE do not send MIME/HTML versions across. 3 reasons why I say this. 1. Because you duplicate the message 2.
