MCE in this context is not Machine Check Exception, but mce, the “Mode Control Entiry”, a management daemon running under Sailfish OS.

Note also how the log shows this is not a kernel message.

I think what happens is that msyncd, something that deals with calendar, mail and other synchronizations, has “asked” MCE to prevent device sleep, and MCE reports that to the journal.
There might be a bug (after all 239994ms is about four minutes), but from here this looks like normal operation.

Thanks for looking into it.

Your analysis makes sense to me, as my Nextcloud sync seems to not working properly.
And the mce errors regarding pulseaudio I was getting later are also explained with this.
I don’t get why this is regarded as an error. But whatever.

Have a great day and thanks again.

Mind hitting that “Solution” button so this Bug Report drops out of the Open Bugs list? Thanks!
