akonadiserver crashes on one of the test systems while starting. We see akonadi_control trying to restart the server a couple of time, which always exists with error code 1, until it gives up.
The server error log looks like this:
Database process exited unexpectedly during initial connection!
executable: "C:/Program Files (x86)/Kontact E5/bin/mysqld.exe"
arguments: ("--defaults-file=C:\Users\kolab\AppData\Roaming\.kontact\.local\share/akonadi/mysql.conf", "--datadir=C:\Users\kolab\AppData\Roaming\.kontact\.local\share/akonadi/db_data/", "--shared-memory")
