Connection bouncing up and down between MTA's

I'm in the midst of testingversion compatability on a test GW2012 system.
The main domain hosts a PO with 5 user accounts and web access.

I'm testing a GW 8 domain/MTA against the main GW2012 domain and the GW8 MTA shows the connection closing and opening about once a minute.

Although there are 5 user accounts on the GW2102 PO, there is no user activity on the system, so all the messages I see in the logs are administrative in nature.

According to GW2012 documentation, a GW 8 MTA should have no problems communicating with a GW 2012
MTA, so I'm not sure if this is a compatability issue or something else.

The Gw8 MTA logs show a lot of both "Domain now open" and "Domain now closed" messages.

The Gw2012 MTA logs show a lot of "Domain now open" messages, but no "Domain now closed" messages.


If I run both MTA's with the --show command line option to display the server console, I see the following:





The GW8 logs also show this error regularly
10:24:46 F489 ADM: Error [8209] processing message

The only reference I find for that error code is tied to path not found issues when an MTA is trying to talk to a PO.
Since the GW8 domain has no PO, and isn't directly linked to the GW2012 PO, I can't see that being the the issue.

I have attached samples of both MTA logs that are from the same basic time frame.
Other than the 8209 messages, I don't see anything that jumps out at me.
Both logs show some level of successful communication, which would lead me to rule out basic configuration problems, like the wrong IP address or port number.

Possibly relevant info:
Both servers are OES 11SP2.
I have the firewalls disabled on both servers
Both servers are virtual machines running on the same host server.

I guess the next step is wiping out the GW8 domain and replacing it with a GW2012 version to see if that changes anything.

    How are these systems connected?
    I'm assuming they are different GW systems with different system names and
    that these two systems are connected as external systems to each other.
    Are they each in their own eDir trees?
    Please confirm, or explain which method you have to connect them.

    How have you tested other conntectivy between these servers?
    Pings? Ssh sessions? Scp copies?

  • I apologize, Andy.
    After re-reading my post, I realized that I should have been much more specific.
    The GW 8 domain is a sub-domain in the same GW system.

    These two OES11 servers are in their own tree on a test network.

    The GW2012 server was originally the only server in the tree, so from the eDirectory standpoint, it's the CA authority, master partition holder, iManager host, etc.

    From the GW perspective it holds the primary domain, holds the only PO and hosts the web access.

    The second server was added to the test tree in an OU and hosts a secondary domain in the same GW system.
    So communication between the domains is the standard port 7100 connection.

    As a follow-up, I removed the secondary domain and its attendant MTA, then installed a GW 2012 secondary domain and MTA.
    Here's all the activity that is seen on that MTA after 20 hours of existence:



    I've had odd installation issues with GW on Linux in the past, so I don't consider an installation oddity as outside the realm of possibility.

    I'm going to remove the GW2012 secondary domain and try a version 8 subdomain again to see if the same issues show up.

    I also recognize that it's also not outside the realm of possibility that all the activity I saw was merely cosmetic.

    Since I didn't have anything other than the domain set up, I have no idea if there would have been any real issues with any other GW component (post office/users, gateway, etc..) I would have placed in that secondary domain.
  • Well, there's definitely something about GW8 that is unloved by GW2012.
    I deleted my 2012 secondary domain/MTA and tried a GW8 secondary domain/MTA again.
    The same activity is seen on the GW8 MTA and the GW2012 MTA now shows this:



    Neither of the MTA's show any messages as undeliverable, so again, it may simply be cosmetic
    I've attached a new log file from the GW2012 MTA showing the cyclic behavior from that perspective.

    Was your primary ever a GW8 domain?
    I know that a GW8 system that is partially upgraded to GW2012 works
    just fine (been there, done that, is a needed part of larger system
    upgrades, didn't get a t-shirt)
    The whole point is that if you are starting to upgrade a GW system to
    the next version, that A) the primary was the old version at one point,
    and B) that any new domains would be of the new version to match what
    the primary domain is.

    So why are you trying to have the GW8 domain running? Perhaps there is
    a better way.
    If needed, then the real way to test would be to start with an all GW8
    system with two domains, then upgrade the primary, see that things
    still work well between the two, then add a third domain that is GW8

    To troubleshoot your exiting system, activate the web interfaces to the
    MTAs and then check the links pages from each one. They should be
    pointing to each other via IP.

    Interesting that this newest log shows the full host path. I'm assuming
    you just forgot to cleanse it this time and not some other thing
    happening.
