Using trunk and a gmail dimap account.

I'm not sure how to understand everything, let's try :-)

1/ the resources gets all the messages and periodically checks out if the flags are not altered.

2/ then arrives this:
akonadi_imap_resource_1(15265)/kdepimlibs (kimap) ImapResource::onSelectDone: UIDNEXT check failed, refetching mailbox (in imapresource.cpp:1682)

at this point, I have:
messageCount =  5621 // realMessageCount =  5621                       
oldNextUid =  7142 // nextUid =  7147

Akonadi::ItemSync::setFullSyncItems is then triggered (the '-1' is 'd->mTotalItems' in kdepimlibs/akonadi/itemsync.cpp)

the imap resource becomes unresponsive after this line (no more output):

Unhandled response:  "65068" "NO ImapParserException: Unable to read more data

the akonadi server then begins to complain:

Attaching some terminal output, I did split the imap_resource, akonadiserver and kmail output.
Comment 1 Kevin Ottens 2010-01-25 11:45:28 UTC 
Which revision are you testing against? I tried reproducing it this morning without success...

The procedure I used to try reproducing is the following:
 - First sync one of the folders (that's the one we'll be using for the testing) in the resource (using akonadiconsole for instance);
 - Then sync the same folder using another IMAP client (which uses a separate connection, so be sure it's not going through the same akonadi resource instance than the one under test), personally I use an old non-akonadi enabled KMail with an online IMAP account;
 - Using the second client add a new message in the folder, and remove one of the old ones;
 - In akonadiconsole, sync again the folder used for the tests.

Doing that I indeed trigger the "UIDNEXT check failed, refetching mailbox" condition, but then it completes the refetch just fine.

Comment 3 Christophe Marin 2010-01-26 19:35:34 UTC 
Additional notes:

- It doesn't always happen in the same imap directory, the log in the comment above comes from a directory with personal emails. When I restarted akonadi it failed in different dirs.

- If I try to attach gdb to the process, I just get this (using the weekly Qt snapshots from openSuse) :

(Using akonadi trunk and Qt weekly snapshots from opensuse)

More debug:

the throw exception comes from /kde/src/kdesupport/akonadi/server/src/imapstreamparser.cpp:162

when reaching the "NO ImapParserException: Unable to read more data" message:

Comment 5 András Manţia 2010-05-07 11:16:54 UTC 
I also see random hangups of the imap resource. It doesn't crash, but just stays downloading at X%, and I have to restart the akonadi server to get it work again and hope it will finish that time.
Comment 6 Volker Krause 2010-05-19 08:50:25 UTC 
Should be fixed with 1125884 and 1126181.
