Bug ID: 338370
Summary: Kmail2 (4.14rc) with gmail too many simultaneous imap
Platform: Kubuntu Packages
Assignee: kdepim-bugs at kde.org
Reporter: rjvbertin at gmail.com
With the latest (4.13.97) packages in the Kubuntu 14.04 backport PPA, kmail2
has become (almost) unusable with my main gmail account. I've always had the
occasional failure due to gmail's limit on the number of imap connections
(though I *think* it started with 4.13) but now this has become a serious
blocker. There is some voodoo involving various combinations of offlining the
account and restarting the akonadi server and/or kmail, but it never takes long
before I get bitten again.
I do not only have my Linux workstation on which I handle email, but also an
Android tablet, an iPhone and a Mac workstation, so the gmail account has a
number of filters that sorts incoming mail in folders on the server. Because of
that and gmail's 15 connection limit, it is extremely important that each
client behaves and doesn't just multiply the number of concurrent connections
(for scanning all those folders in parallel, for instance) without ever closing
them immediately when done.
Thunderbird has the same issue with its default of 5 simultaneous connections
max. per server, but it allows to dial that value down. With 1, I can avoid the
I have thus gone back to using Thunderbird and removed all my kmail/akonadi
imap accounts (since they cannot be deactivated permanently otherwise) in hope
and waiting for better days.
NB: the issue doesn't appear to occur (or MUCH less frequently) when just
letting the akonadi resources run without kmail running. To me this suggests
that it's something in the way kmail talks to the akonadi resources that
triggers the issue.
Is there a way to limit the number of simultaneous imap connections, either in
kmail or in akonadi?
