  • [SOLVED] Mail delivery issues for POP/IMAP in latest Grommunio releases

@crpb I created a ticket a while ago and linked some threads from the forum into it.
But the response time is quite slow.

crpb most people should be back from the summer vacation

Some grommunio developer come back this weekend.

A customer using IMAP told me: Last weekend's "supported update" fixed this.

But, big question, which code change in grommunio introduced this issue?

  • crpb replied to this.

    well, it is not fixed on my side.
    Rocky Linux 9 - Aarch64 - up to date supported release

    Same here, issue still persists
    Debian 12 - Supported Repo
    gromox 2.30.85.4d271dc-1+2.1 amd64

    @Vincent I am relieved to hear that, that someone else has the issue on x86_64 as well.

    @jengelh can you please comment on this?
    Is there something we can do to help debug it further?

    @WalterH Can you please investigate about the setup of your customer and if he might still have the issue?

      I updated to the latest Cummunity Edition today. Now I also have the problem with the massively delayed IMAP synchronization. :-(

      EDIT:
      Grommunio appliance (SuSE iso) on Proxmox/qemu vm with 16G RAM
      gromox 2.32.0.ge7685dd-lp155.12.1
      grommunio-imapsync 2.264-lp155.1.1

        Joerg grommunio-imapsync

        is a migration tool, have nothing to do with this issue.

          WalterH Thanks Walter for the hint. Is there any other information I can provide to help solve the problem?

          WalterH But, big question, which code change in grommunio introduced this issue?

          The release around june 6th iirc.
          But which codechange exactly.. no idea..

          @crpb do you have the tools to do a bisect?
          Maybe that could tell us, where to look, but I bet it might be extremely difficult now, to build such an old gromox version?

          Please note: if you have IMAP issues with iOS 18, this is an iOS issue.

          Hi together... same problems here... sometimes IMAP messages are show up fast, sometimes after a few minutes and sometimes only if i restart gromox-midb.service and gromox-imap.service.

          Testing if midb_reload_interval=1minutes helps... somehow... The messages are shown after 7min with that.
          But im never realy sure if messages never show up so i double check the mailboxes very often now... puh...

          No SQL Warnings here. "Only" the problematic IMAP communiation.

            morbificagent Last night a new community edition 2.33 was released. Please test if this release solves this issue?

            Well maybe these are better news: Please check gromox-2.33.30.x0db9c00 from devel repositories (https://download.grommunio.com/devel/). A simple rpm -Uvh of only the gromox package should do.

            The devel branch currently boasts a (yet unpublished) relevant fix which whould solve this issue, commit message:

            midb: resolve "inside a readonly TXN" warnings during message deletion
            
            An implicitly started transaction stays open until the cursors have
            reached the end of the data set. Just like e.g. fread(3), it is not
            sufficient to read the exact number of rows/bytes — it really takes
            that final step()/fread() call for the end-of-data/end-of-file flag
            to be set.
            
            References: GXL-537, GXF-1738, GXF-1769, DESK-2301, DESK-2311
            References: DESK-2402, DESK-2421, DESK-2436, DESK-2449

            It specifically deals with the notification and stems from our full-transaction-based rebuild.

            Please let us know of any results from your side.
