Iam not sure if you are alluding that it could be a flow control issue in checkpoint service? Also, you have increased the MDS_SOCK_SND_RCV_BUF_SIZE=33554432, that's a very big value, and i don't know if there's any benchmark data associated with that size! Mahesh could comment on this.
A question i have is, did your exercise succeed when using the default buffer sizes for MDS_SOCK_SND_RCV_BUF_SIZE and DTM_SOCK_SND_RCV_BUF_SIZE?
