[rt-users] Scrips dying now and then when sending email

[Sternberger, Sven]

Hello!

I have an really ugly bug and I can't find the reason.

The bug is: From time to time (once a week). For 5-15sec  RT dont send mails created by scrips. This could strike one but also several emails.

I see in the logs lines like:
RT: [14868] Use of uninitialized value in method with known name at /opt/rt4/sbin/../lib/RT/Action/SendEmail_Local.pm line 180.
RT: [14868] Use of uninitialized value in method with known name at /opt/rt4/sbin/../lib/RT/Action/SendEmail_Local.pm line 180.

with 4.2.10 I got 
"via package RT::Action::SendEmail" or "via package RT::Action::Notify"

since I updated to 4.2.12 (last week) I get
"via package MIME::Head"

Environment:
virtual vmware machine
Ubuntu 14.04 / 
apache 2.4.7 /
mod_perl2.0.8
perl 5.18.2

My assumpotion/next ideas are:
1.) I don't configured the worker in Apache. The default seems to be mpm_event for Ubuntu 14.04 . So may mpm_prefork???
2.) Ubuntu comes with mod_perl2.08 maybe I upgrade to 2.09??
3.) I made some small changes in the code (really small I just removed a check). This produces a lot of 
lines like "Subroutine SetRTSpecialHeaders redefined at /opt/rt4/sbin/../lib/RT/Action/SendEmail_Local.pm:"

Files I modified
 /opt/rt4/lib/RT/Action/SendEmail_Local.pm 
 /opt/rt4/local/html/Elements/Footer
 /opt/rt4/local/html/Ticket/Update.html
 /opt/rt4/local/html/Ticket/Create.html

Changes I made in SendEmail_Local.pm:
816,823c816,822
<     # removed for q2q
<     #$self->RecipientFilter(
<     #    Callback => sub {
<     #        return unless RT::EmailParser->IsRTAddress( $_[0] );
<     #        return "$_[0] appears to point to this RT instance. Skipping";
<     #    },
<     #    All => 1,
<     #);

For really appreciate any help
best regards!
