After updating to kmail2 v5.2.3 and the latest version of akonadi in openSuSE
Tumbleweed, kmail and akonadiconsold continuously lose connection to the
akonadi server for 10-45 seconds at a time. This appears to happen at intervals
of anywhere from 10-60 seconds. 

Running akonadiconsole from the command line reveals the following output;

The dropouts seem to coincide with the akonadicore_log socket errors. 

Akonadidb is running on mysql. Using IMAP with dovecot (on a server on the same
network) and gmail (remotely). 

Reproducible: Always

Steps to Reproduce:
1. Open kmail
2. Wait - kmail reports "The akonadi personal information management service is
not running...."
3. Sometimes the connection is re-established, but sometimes it requires a
forced restart by clicking the "start" button. 

Actual Results:  
Kmail (and akonadiconsole) lose connection to the akonadi server.

Expected Results:  
The connection should be stable.
