Thanks Scott, I did email postfix-users with subject "NULL pointer deref in pcf_check_dbms_client() with unreadable map file", but I'm not subscribed. Checking the archive at https://marc.info/?l=postfix- users=1=201805=2 doesn't show my message, so I guess I should subscribe.

And this is new in 3.3.0.

[Bug 1753470] Re: Postconf segfaults every 5 minutes
The crash happens in vstream_fileno(fp), because fp is a null pointer:
if ((fp = vstream_fopen(cf_file, O_RDONLY, 0)) == 0
&& errno != EACCES) {
msg_warn("open \"%s\" configuration \"%s\": %m",
dp->db_type, cf_file);
myfree(dict_spec);
return;
}
if (fstat(vstream_fileno(fp), ) == 0 && !S_ISREG(st.st_mode)) {
msg_warn("open \"%s\" configuration \"%s\": not a regular file",
dp->db_type, cf_file);
myfree(dict_spec);
(void) vstream_fclose(fp);
return;
}
vstream_fopen() did return 0 and errno was set to EACCES, I don't know
why that check is excluding the permission problem. I emailed upstream
(couldn't find a bugtracker for it).

[Bug 1753470] Re: Postconf segfaults every 5 minutes
Do you have mail in the queue? -> sudo mailq Do you have another 5min cron job that is perhaps failing and therefore sending an email? Can you see any ownership and permissions problems in the postfix directories? Try "sudo postfix check", and maybe do a quick manual inspection in /var/spool, /var/lib, /var/mail directories Do you have users and groups coming from a network source, like ldap, nis, ad, and maybe the postfix user or group is mixed with that? Can you try running that postconf command as the postfix user, or as root if your previous attempt was as postfix or a regular user? Something like "sudo -u postfix -H postconf -h queue_directory" Thanks -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in Ubuntu. https://bugs.launchpad.net/bugs/1753470 Title: Postconf segfaults every 5 minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1753470/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Thanks for filing this bug in Ubuntu. Do you know what is making this call every 5min? I couldn't locate a cronjob about it.
