Hi everybody, I seem to need help with an error
free(): double free detected in tcache 2 at the gromox-delivery service startup

After the latest update 22. Feb 2025, to gromox 2.42.2.gc035dfb-lp155.3.1, gromox-delivery service fails to start
repeated block in output of journalctl -fu gromox-delivery -n 1000:

Looks like programming error, or other idea?
Restarts of the service, system did not help

How you can help me

  1. What is this tcache? Can it be cleared, can you share the command?
  2. I would like to rollback to previous version, but it is not in the repository. Can you point me to alternative?

Similar issue on Debian with gromox 2.42:
delivery[4038074]: double free or corruption (out)

to be more precise:
2.41.97.gd9eb9c8-1+21.1 already has the issue, while
2.41.16.gee901f3-1+15.1 is working as expected.

    confirmed.

    it is possible to "reanimate" the service with tmalloc4.
    But this only leads to multiple duplicates delivered to mailboxes

    Any damaged file in the delivery queues?

    ls /var/lib/gromox/queue/*

    Checking the subfolders, I see a few files in /var/lib/gromox/queue/save, but they are dating back by at least one year.

    But I had the same situation when using the faulty versions of grommox-delivery, that emails did show up in inboxes 10 times or even more for the same email. They did not look corrupted and could be cleand up via the regular MUA (Outlook).

    Following the docs here https://docs.grommunio.com/admin/operations.html, I moved the messaes from .../save to .../mess to requeue them. 2 of the messages have been processed immdeately, the others remain in .../mess.
    But no logs in "journalctl -b -u gromox-delivery", "/var/log/gromox/gromox.log" or even "/var/log/mail.log".

    I tend to delete the stuff in .../mess, as having a look into the files on the shell did show that these are no valuable emails.

    weini
    mmh any chance to replace 2.42.3 with the working one ?

        sadly I have the same situation since last week (only on my home Testlab with community Edition, all supported installations work fine), so I realy think there is s.th. not ok with the aktuel grommunio-delivery packet (EL9 )

        emstersj Sure, but you need the old version. So check your backups, your apt cache (on Debian) and the like. Downgrading is easy, if you have the package file.

          mmh i think i got fooled : )
          i always made updates with. zypper ref && zypper up
          leading to some version mixup..
          firing grommunio-update upgrade .... all fine now
          no bloody memory leaks

          anybody to confirm this ?

          Confirm today's gromox-delivery 2.42.10.gec8e477 solves the problem on openSUSE appliance. Thank you
