This problem could be caused by a cam communication problem with big parcel size.
From Domain Manager, try camping to target machine with different size.
Example if target machine is 10.1.2.3
camping -s 1024 10.1.2.3
camping -s 2048 10.1.2.3
camping -s 4096 10.1.2.3
camping -s 8192 10.1.2.3
camping -s 10000 10.1.2.3
If camping works with 8192 but not with 10000, then execute this on Domain Manager to set the CAM fragment_size to 8192 :
camconfig fragment_size=8192
camsave explicit
Then delete the cam queue :
camq -d -n 10.1.2.3
and try again the deployment.
