The 1611 is sort-of a generic error indicator. It means that the remote agent process exited with an unexpected code, with the unexpected codes being 59 and 5 on your two targets. The unexpected codes are Windows system error codes.
5 is normally:
ERROR_ACCESS_DENIED
5 (0x5)
Access is denied.
However, 5 could also mean that there was an access violation on the target, which would essentially mean that the remote agent crashed unexpectedly. If this were the case you would see something in the application event log of the target computer. Normally an ‘Access denied’ error would be reported differently in BatchPatch, which is why I suspect that in this case you might instead be dealing with an access violation unexpected crash of the agent.
59 is:
‘ERROR_UNEXP_NET_ERR
59 (0x3B)
An unexpected network error occurred.’
I would suggest that you start by rebooting the target computers. Then see if it happens again. You might find that these are transient issues, especially if you have not had any issues running BP with these computers in the past.
