           Summary: Akonadi IMAP backend huge memory consumption.
           Product: Akonadi
           Version: 1.4.0
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP resource
        AssignedTo: ervin at kde.org
        ReportedBy: alejandronova at gmail.com
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Version:           1.4.0 (using KDE 4.5.0) 
OS:                Linux

After retrieving a folder with ~3 GB of mail, ~15,000 mails, with some
attachments, the akonadi_imap_resource process is using 487 MB of RAM and
doesn't move from there. Also, CPU usage for it spikes quickly when it checks
for new mail.

The memory usage is kept after reboots, and grows slowly, indicating possible
memory leaks.

Tested with Akonadi/KDE-PIM 4.4.92.

Reproducible: Didn't try

Steps to Reproduce:
1. Download the sample data.
2. Watch the memory consumption and CPU usage skyrocket.



I need further instructions to debug this. This could be a hellish combo of
god-knows-what, but I'm filing this to get instructions and to track the issue
properly.
