Upgrade failure of secondary MDS or MLM when Jumbo HFA is already installed on primary Technical Level
  • After installing Jumbo HFA on primary Multi-Domain Management (MDS) or Multi-Domain Log (MLM) server, upgrade of secondary server to R80.10 via CPUSE reverts back in more than 30 minutes after starting it.

At some moment MLM starts waiting for MDS to connect to it, so MLM would get latest objects database. For some reason, traffic arrives from the MDS (could be seen in tcpdump), but synchronization does not succeed without valuable entries in cpm_for_cpdb log.
