MailScanner: Process did not exit cleanly, returned 2 with signal 0

Hello,

Our mailscanner server all of sudden stopped processing incoming and outgoing emails. I checked maillog and saw:

Here are the software versions:

Code: Select all

MailWatch Version: 1.2.10
Operating System Version: CentOS Linux 7.9 (Core)
Postfix Version: 3.8.1
MailScanner Version: 5.1.3
ClamAV Version: 0.103.10
SpamAssassin Version: 3.4.0
PHP Version: 7.4.33
MySQL Version: 10.3.39-MariaDB

I have tried 'yum update', deleted /var/spool/Mailscanner/incoming/Processing.db and restarted mailscanner but none helped.

I would greatly appreciate if someone can point me to the right direction.

Thank you.

Hi Sarah,

Thank you for helping me. I ran MailScanner --debug and got followings:

Code: Select all

MailScanner --debug
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US.UTF-8",
        LC_ALL = (unset),
        LANG = "en.US"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

I followed all the suggestions (except the upgrade part) and mailscanner is still broken.

Any more suggestions?

Thanks,

James

Does the WHM MSFE show you are running the latest version of everything? Is this a cPanel server? I have a feeling it is a very old install because of the mention of the Processing Attempts database, which we disabled ages ago. You may need to uninstall and reinstall MailScanner and MSFE. There are articles for each in the knowledgebase. If you'd like more help, please log a ticket on the helpdesk:

Hi Sarah,

I did upgrade to the latest version and everything works now.

Thank you so much for your help!
