Sudden problem : Can't use an undefined value as an ARRAY EmailParser.pm

RT Users

Suddenly at 8am this morning my RT 3.6.6 has stopped accepting email
requests. I have checked for any updates to perl etc but have found
nothing, debug output shows :

cat /usr/bin/test |/etc/smrsh/rt-mailgate --queue itsupport --action
correspond --url http://rt.adastral.ucl.ac.uk/ --debug

Connecting to http://rt.adastral.ucl.ac.uk//REST/1.0/NoAuth/mail-gateway
at /etc/smrsh/rt-mailgate line 102, <> line 1.

Can’t use an undefined value as an ARRAY reference at
/usr/local/rt/lib/RT/EmailParser.pm line 626.

Stack:
[/usr/local/rt/lib/RT/EmailParser.pm:626]
[/usr/lib/perl5/5.8.8/Carp.pm:269]
RT server error.

The RT server which handled your email did not behave as expected. It
said:

Can’t use an undefined value as an ARRAY reference at
/usr/local/rt/lib/RT/EmailParser.pm line 626.

Stack:
[/usr/local/rt/lib/RT/EmailParser.pm:626]
[/usr/lib/perl5/5.8.8/Carp.pm:269]

I have looked to see if there are any changes in sendmail, smrsh etc but
again found nothing. Can anyone help me with this?

Many thanks,

Neil.

I’ve never had this problem, but assuming your
[/usr/local/rt/lib/RT/EmailParser.pm:626 is:

sub DESTROY {
my $self = shift;
File::Path::rmtree([@{$self->{‘AttachmentDirs’}}],0,1);
}

Assuming the email you are passing through is valid and has
attachments, AttachmentDirs should have been set in _SetupMIMEParser.
I would do two things:

  1. Make sure the user running mailgate does not have permission issues
    in /tmp.
  2. Put some comments around the code in _SetupMIMEParser and see is
    tmpdir is being set, what is it being set to, and if AttachementDirs
    is being pushed in properly.
