  • 1.  ATC TT Arrival Buffer Full

    Posted Oct 13, 2017 07:17 PM

    I know of at least three of our customers who are experiencing the situation where the ATC TT arrival buffer is filling and then APM begins writing constant messages to the logs.  It seems that APM 10.5.x is creating more TTs than previous versions, but it would be nice to have some feedback to validate or reject that assumption.

     

    The messages in the logs look like this:

     

    8/04/17 12:25:46.847 PM EDT [INFO] [PO:WatchedAgentPO Mailman 2] [Manager] TransactionTrace arrival buffer full, discarding trace(s)

    8/04/17 12:25:47.713 PM EDT [INFO] [PO:WatchedAgentPO Mailman 5] [Manager] TransactionTrace arrival buffer full, discarding trace(s)

     

    Performance seems to suffer and even shifting into legacy (non-transaction) mode doesn't help.

     

    Has anyone out there experienced this and have any kind of solution?

    Hi Cary,

    Is this with10.5 agents? What is the exact version/build of the agents being used?

    From the EM/ATC performance side there are some Team Center improvements with a fix that went into 10.5.1 HF#20 & 10.5.2 SP1.

     

    Thanks

    The problems are seen with EMs at 10.5.1 at any hot fix level. The bigger problem is that one customer has 9.1.4.0, 9.6.x, and 10.2.0.27 agents. It is not a possibility that these agents will get upgraded this year, so a better/more comprehensive solution needs to be provided.

     

    Changing the sample rate interval on the collectors worked on some agents, but not others of the same build. These collectors are being flooded with sample and normal traces.

    There are differing agents, and no configuration changes have had any effect, at least on one of my customers.

    Lynn,

     

    This is a 10.5.2 environment, but not all of the agents are at 10.5.2.  One of the customers is waiting for SP2 to release (I think they have it now) so they can install and see if the issues are resolved or reduced.
