Bug ID: 396663
Summary: Imap resource crashes when large amounts of emails is
moved/deleted
Product: Akonadi
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: IMAP resource
Assignee: kdepim-bugs@kde.org
Reporter: x...@x-s.com.pl

suspicious changes.dat file
I'm experiencing crash of imap account agent on my work account.
It happens when large amount of mails (in hundrets) is moved/deleted via
filtering or by hand.
KMail deletes messages locally then it tries to sync changes.
Then akonadi_imap_resource process usage of CPU and mem skyrockets and finally
process crashes with SIGABRT.
Observed anomaly: agent_config_akonadi_imap_resource_8_changes.dat gets gets
larger than changes.dat files for other imap accounts (file attached)
To recover I have to stop akonadi, remove changes.dat file and start akonadi
again.
Maybe it is trying to delete messages that not exist anymore, or file just gets
corrupted.
Setup:
Fedora27
plasma: 5.12.6
KF5: 5.47.0
Apps: 17.12.3
Akonadi is using postgres db backend.
