Hi Mier,
As the error message in the system you have for the agent is the htyp you have is not supported.
the host is running on sparc64 machine and have installed agent for sparc64 as well...
As you mention you have installed agent for sparc64 before.... I don't know if you have install those on this same machine, where this DLPBATCH is install or not. I would assume those other agent are on a different machine than this? If that is the case, it might have a slightly different HW/SW flavor then this machine.
The log show this for the HW/SW
20181030/065436.513 - U02000020 Environment: Hardware = 'sun4v/32'.
20181030/065436.514 - U02000021 Environment: Software = 'SunOS'.
20181030/065436.515 - U02000022 Environment: SW version = '5.11'.
The first and easiest thing to confirm first is the htyp list and see if you have one for SunOS that listed version above in your htyp. The UC_HTYP table will have the list of HW/SW available for your system. If there isn't one for your the version above, then you will need to contact support and they can work to create a new htyp file for you to load into the database.
Also as Wolfgang have commented below, you might want to check and see if you have any firewall/rules or other component that for the connection to disconnect after 5 minute.
PS: I have put your logs file in a text file and attached to your comment, so that it will be easier/cleaner to view this thread.
