Cannot upgrade beyond v0.11.4

[namsral]

Issue Description

When upgrading from v0.11.4 to v0.12.5 my non admin accounts are no longer working using Apple Mail, authentication fails in SMTP IMAP protocols. I haven't tried other clients but the webadmin lists the accounts without names and details so it seems something is wrong at the server side.

The logs report the following error messages:

I have tried to export/import my stalwart data but it fails with a segfault:

% systemctl stop stalwart-mail
% stalwart-mail --config config.toml --export /var/lib/stalwart-mail/export
% chown -R stalwart-mail:stalwart-mail /var/lib/stalwart-mail/export

I acknowledge that:

• I have reviewed the documentation and FAQ and confirm that my issue is NOT addressed there.

I resolved the issue by importing the exported data on another server and copying the result back to the main server.
My best guess is that stalwart-mail import failed with a segfault due to memory exhaustion as the server has less than 4GB RAM, running on aarch64 architecture.
