Description Ariadne Conill 2020-06-01 03:13:21 UTC

After suspending to RAM, akonadi-server 20.04 falls over with MySQL errors and crashes on Alpine Linux edge.

Monitoring the debug log yields:

It remains dead after restarting.  If I kill all Akonadi processes manually (but not mysqld) and run "akonadictl start", it recovers and behaves as normal.

I'm not sure what further information I can provide.  Unfortunately I don't have any logs for the crashed processes that I am aware of.

Comment 1 Martin van Es 2020-06-07 08:12:13 UTC

I, too am seeing Akonadi crashes that seem to be related to suspend/resume cycles. It is impossible to restart the akonadi process unless I kill the mysqld-akonadi process and then see no crashes untill at least the next day (which involves a suspend/resume cycle).

Comment 3 Martin van Es 2020-08-03 07:32:47 UTC

I switched Akonadi backend to postgresql a couple of weeks ago and have not encountered another crash ever since. So far, so good.
