After further problems, I still had the problem but I do now have spotted why
(I wish so).
I realized that every e-mails from internal users actually comes as normal
e-mail in the public folder, so as IPM.Note, and everything was working
perfectly.
Once an e-mail came from any external SMTP address, the public folder created
it as a Post publication, as an IPM.Post.
OTRS doesn't seem to support this kind of form, so you must change the default
form to a standard e-mail type.
If you are using Microsoft Exchange 2003 or any earlier version, to fix it, you
must follow the instruction from the following Microsoft's Knowlegde Base link:
http://support.microsoft.com/?id=817809
Otherwise, it would be nice for OTRS to add this form type for reading the
received mails.

Subject: Re: [otrs] CPU overload on PostMasterMailbox's PID Deletion
Hi everyone,
I finally noticed that a loopback was created since the e-mail I configured in
OTRS was the same as the one transferred by the Public folder from my Exchange
2003 Server. I've created this for backup purposes.
Well, here's the situation:
1- I've created an Exchange public folder with a rule inside showing that any
received e-mail with the e-mail address in the "To" field should transfer the
intact e-mail to OTRS throught a specified system account (with a different
e-mail address);
2- Whenever an element (like a note in this case) was created inside this
public folder, the rule thought it was an e-mail and sent it the the OTRS
account with the "From" of the public folder's smtp address which was equals to
the smtp e-mail address configured in OTRS;
3- Since we configured to make an automatic replies for the new tickets, this
would make an infinite loopback where for each hour, the PID was deleting that
job but retrying right after. This had both the impact to block any other new
e-mails and overloading the CPU by recreating an additionnal "perl.exe" at each
hour.
Notice that the 10 minutes fetching was not running since it considered that
the PID was already running, which is ok. But once we entered in another hour
for the deletion of the old process, it had the problem to add one, where all
of them were looping and freezing any other actions on the server.
I wish this information could be useful for any other person who may experiment
this kind of problem!

Subject: [otrs] CPU overload on PostMasterMailbox's PID Deletion
Hi everyone,
I'm currently new with OTRS and I really like the software but I have a little
problem..
I'm running OTRS 2.4.7 with StrawberryPerl under Windows through a VMWare
machine and I've noticed that every hour, when the PIDCreate remove the PID
from PostMasterMailbox, the CPU is overloading for an unlimited period of time.
Once we enter a new hour, like 1h00pm, there's a new "perl.exe" running, using
all the CPU and keeping always the same number of memory space.
I'm not sure about anything but from your opinions:
Does it could it be possible that using IMAP could has an impact? I've notice
that most people uses POP3..
Does having around 33 postmaster filters could slow down the process'
completion (we only receive around 1 or 2 e-mails every half an hour)?
Does using IMAP provide no e-mail deletion then search for new e-mails, so as
the mailbox grow, the PostMasterMailbox look at every e-mail?
Should I provide the IP address or the ServerName of the Mail server?
I also had this CPU problem with OTRS 2.4.6 with OTRSPerl. I've upgraded and
changed the Perl interpreter in case that the problem could be fixed...
Here's what I get from the OTRS log file:
[Mon Mar 8 10:00:09 2010][Notice][Kernel::System::PID::PIDCreate] Can't create
PID GenericAgent, because it's already running (SERVERNAME.com/3016)!
[Mon Mar 8 10:40:08 2010][Notice][Kernel::System::PID::PIDCreate] Can't create
PID PostMasterMailbox, because it's already running (SERVERNAME.com/3008)!
[Mon Mar 8 10:50:06 2010][Notice][Kernel::System::PID::PIDCreate] Can't create
PID PostMasterMailbox, because it's already running (SERVERNAME.com/3008)!
[Mon Mar 8 11:00:09 2010][Notice][Kernel::System::PID::PIDCreate] Removed PID
(PostMasterMailbox/SERVERNAME.com/3008, because 1 hour old!
*Exactly at the last action, the process starts and never stops.
Thank you in advance for any of your help!
