Maia Mailguard can't find Fork or threads

BobWalter

I installed postfix/dovecot/maia on FreeBSD 8.2 amd64. All works correctly except the Maia cron job that wants fork or threads. I verified that perl forks is available (installed from ports collection), however the maia configtest as well as the cron job that wants forks/threads can not find it. Since there are many FreeBSD maia installs, I am wondering if there is an issue with the amd64 version.

I contacted the maia port manager but he failed to answer. Can anyone help me untangle this?

Thanks,
Bob
 
Actually, there aren't error messages per se. If I run configtest.pl, it just hangs. By process of elimination (commenting out tests one at a time), I discovered the test for forks is where it hangs.

When I run # /var/maiad/maia/scripts/process-quarntine.pl --learn --report
I get
Code: 
"Perl module 'forks' not installed, and 'threads' support not available"

The code generating this message is:
Code: 
# Try to use the forks module first
eval {
   require forks;
   forks->import();
};
if ($@) { # fall back to using threads if available 
	eval {
	   require threads;
	   threads->import();
	   $use_threads = 1;
	};
	if ($@) {
		die ("Perl module 'forks' not installed, and 'threads' support not available.");
    }	
}

I verified that the ports collection has forks installed.

I commented out the last "if" clause so the script would run even without detecting forks or thread support.
When run from the cron tab, the process never closes. I killed the running process and then ran the script from the command prompt.

I changed the maia log level to 'debug' to see what the output would be. As you can see, the script appears to be processing mail in some respect.

I eliminated a lot of duplicated lines.

Apparently some work is being done. I have not received any confirmation emails from SpamCop yet. If the script is, in fact working, I am still unable to run it under cron since the job never terminates.

It would be my hope to figure out how to get this script to see forks, failing that, getting the job to complete under cron would be a big help.

Thanks,
Bob
