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

Unfortunately, everything is back to (bad) "normal" this morning. For some reason, it seems worse now. I'm currently only receiving one email via IMAP, and then it's dead silence. Restarting the services gives me emails for ohne time and then... again dead.

As a workaround i have made a cronjob to restart

gromox-midb.service gromox-imap.service

Every few minutes... not great but so i get mails.

    GeneralProbe @jengelh can you please comment on this?

    I don't follow the fourm—there is just too much noise in it.
    Current hypothesis is that notifications are getting emitted too early, and midb/imap tries to read a message right then before the message data has made it to the database. All per-mbox operations were previously serialized, but have gained read concurrency in 2.30.

    workaround: gromox.cfg: exmdb_force_write_txn=1

    Here it didn't helped for some reason. Not sure if it's like that because I'm on the dev gromox version at the moment but anyway... Waiting for a general fix which hopefully comes in some days

    Yes, i tried it with and without the midb_reload_interval change via config, was rebooting the services and the whole server and decided to wait for the fix ;-)

    I tested it again right now, it still works as expected.
    Maybe it is stable vs. dev?

    OK. My fault. I had entered exmdb_force_write_txn=1 not in the gromox.cfg. Because I was editing the midb.cfg so often I put it there.

    Now I'm testing with the right settings at the right place ;-)

    Hm... Don't know what I'm doing wrong. It's in the /etc/gromox/gromox.cfg now... Restarted... Doesn't help...

    Downgraded gromox to version gromox-2.33.30.g4a6189a... Still with the exmdb_force_write_txn=1... Doesn't help... It stays the same. One or two new mails are visible via imap, and silence after that.

    Back to my contab restart imap services every few minutes and waiting for better days.

      Can confirm, works on both of my systems for a couple of days now, without any troubles.
      Thank you.
