      We have a current problem in kopano-gateway:
      An unhandled exception is thrown in libkcutil, if gateway ist started with option process_model = thread -
      kopano-process dies upon a first (IMAP)connection-attempt.

      Setting process_model to fork is a work around.

        @umgfoin said in BUG: Kopano-gateway 8.4.0.415 unhandled exception in libkcutil.so.0 with process-model pthread:

        We have a current problem in kopano-gateway:
        An unhandled exception is thrown in libkcutil, if gateway ist started with option process_model = thread -

        Setting process_model to fork is a work around.

        I submitted a fix for it but it has not reached master yet. If you want to compile your self you can cherry-pick https://stash.kopano.io/users/bsimonsen/repos/kopanocore/commits/76acf3f67746517ab379a9494c287f43e9e561d5

        But would expect it to be in master within this week. Corresponding JIRA ticket is here: https://jira.kopano.io/browse/KC-655

        Thanks for reporting!

        Bo

          Hi Bo,
          just updated to 8,4,0,437:
          Pthreaded gateway is back to service again.

          Thanks for fixing.
