KMail: Retrieving Folder Contents

[Timothy Murphy]

KMail hangs on my Fedora-22/KDE laptop every 2 or 3 days
with the above message.

This has occurred with previous versions of Fedora,
but in the past I could usually cure it
by opening AkonadiKonsole, going to the relevant IMAP server,
and right-clicking it off-line and then on-line.

This no longer seems to work.
The only cure I have found is to re-boot the laptop.

I looked at the KDE bugzilla,
and this problem with KMail seems to have been there for years,
without as far as I can see any solution being suggested.

I wonder if anyone knows the cause of this problem;
and even better, how to solve it?

The IMAP (dovecot) server is on the same network on a CentOS-7 machine.
Re-starting dovecot on that machine does not help.
