           Summary: kmail: GMAIL IMAP unusable  on netbook without
                    Disconnected IMAP, ZIMBRA IMAP not quite as bad system
                    resources hammered
           Product: kmail2
           Version: 4.7
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: emgrasso at data-raptors.com


Version:           4.7 (using KDE 4.7.2) 
OS:                Linux

with akonadi and nepomuk enabled the entire netbook is unusable because memory,
cpu cores and network connection are all overloaded by kmail associated
processes and the hard drive thrashes

uninstalling strigi and setting 

sudo chmod -x /urs/bin/akonadi_nepomuk_*

returned system to some usability but drive and network are still being
thrashed.
GMAIL connection not working usably nor accurately

Reproducible: Didn't try

Steps to Reproduce:
Turn on kmail with an IMAP link configured to GMAIL

GMAIL web connection reports 10010 messages in All Mail, 492 Inbox, 
KMAIL api reports 26388 All Mail, 600 Inbox,with false indications of unread
messages

message lists do not populate in kmail and hard drive (and network connections?
browsing gets slow) seem to thrash when I click on a large folder

ZIMBRA web reports 7960 in inbox, both places but message lists and message
displays are slow and message read indicators are erratic

Actual Results:  
see steps to reproduce for additional info

GMAIL messages are not accessible and counts appear garbled

message lists populate slowly or not at all, kmail spends most of its time
displaying "Retrieving folder contents please wait" 
Message read indicators are very erratic

Expected Results:  
a usable email system

System resource use seems better once kmail was left running over night after
the upgrade to Kubuntu 11.10, Zimbra settled down but GMAIL (primary email
source) remains unusable
