    Hi Eric,


    Thanks for that, but still having issues.


    To avoid any confusions - I tried syncing from scratch with
    relay_transactions = true and an enlarged transaction pool capacity.

    Still can't see unconfirmed transactions while the default node that
    bx talks to does see them.


    I believe the log indicates the transaction inventory is saved, like
    this line :

    08:34:38.891999 DEBUG [inventory] Transaction inventory from
    [194.187.96.2:8333]
    dc44299f386f4d76fccef1518dd46724fa299bf0c03cefd03592f46877298112

    08:34:38.892067 DEBUG [inventory] No missing transactions from
    [194.187.96.2:8333] inventory


    I attach my complete configuration file, maybe you can spot
    something here?

It is necessary to enable tx relay, but since you have done
        that (and restarted) there should be nothing else to do as long
        as you are synced past your last checkpoint and haven't set a
        too-small mempool size. It is possible that your mempool is too
        small and is therefore losing txs due to overflow. 
Please
          review the debug log for more insight.

          Missed an important part - bx with the default endpoint shows
          the unconfirmed transactions.

            Hi,


            I'm working with the latest 2.2.0 release, and having a hard
            time getting unconfirmed transactions with fetch-history.

            I'm accessing the query port by both nodejs and bx and I
            don't get unconfirmed transactions back in the result, only
            confirmed ones.

            I thought that some configuration was missing, so I tried
            changing relay_transactions to true, but there isn't any
            change.


            Am I missing something obvious?


            Kobi
