            Bug ID: 363400
           Summary: Akonadi elements stop working with only slightly low
                    memory
           Product: kmail2
           Version: 4.14.10
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: misc
          Assignee: kdepim-bugs at kde.org
          Reporter: mark at vowleyfarm.co.uk

Message and folder operations gradually stop working.
Message filtering stops with "only" 2.1Gb of memory (according to KDE System
Monitor) available (out of a total of 5.8Gb).  There is over 5Gb of swap
available, but this seems to have no effect.

With approx 1Gb of RAM available, messages no longer register as "read" when
they have been read.  At about the same level, sent messages are no longer put
in the folders selected for them but only show in the outbox.

While I appreciate low memory may cause lost of functionality, I struggle to
think of these levels of available RAM as "small".


Reproducible: Always

Steps to Reproduce:
1. Use up lots of memory. NetBeans and Chrome loaded seems to do it.
2. Simply watch filtering stop working.
3.

Actual Results:  
Messages remain in the mailboxes they arrive in.
Using the "Apply all filters on folder" item from the Folders menu makes no
difference.

Expected Results:  
Messages should be transferred to the folders selected for them in the filters
created.
They should work as they do with lower levels of memory in use.
