Hi Jaisree.
Are you doing initial or delta transfer.
What are all the objects you selected during the transfer, Like Material, Vendor, Plant etc.
These Objects are cascaded into blocks and processed in parallel. Your log looks like objects are processed in 2 parallel processes for each object.
Check this link Parallelized Initial Data Transfer - Integration via APO Core Interface (CIF) - SAP Library
Also, just click on the "Yellow ? icon" in the log, it may give you additional information.
