Calibre app shuts down daily

Roodavis · 12-28-2020, 05:48 PM

I have been successfully running Calibre on a Mac Mini since around version 2. Currently this device is running macOS 10.15.7, Calibre v5.8.1. For the last two or three months when I have tried connecting to the server from my iPad to download a new book. I get an error that it can not connect, when I check the device the Calibre app is not running. I restart it and it appears to be running fine. I have started checking it every day and found it not running almost everyday for the past few weeks. I can not find anything in the logs to tell me why or when the app was closed. No power outages have occurred and any other apps are still running. (As a test I have left BBEdit running, just to eliminate an unexpected restart as the issue

Does anyone have any ideas on what I can check to see when or why the app has closed?

I adjusted my energy saving settings as recommended in the bug report and it didn't seem to improve things. I checked the app yesterday morning when I left home and it was running fine. Then around lunch time I tried to connect to download a new book to my iPad and was unable to connect. When I got home in the evening and checked the app was not running and allI could see in the System Log was: "Dec 31 11:58:24 com.apple.xpc.launchd[1] (net.kovidgoyal.calibre.20212[64728]): Service exited due to SIGPIPE | sent by calibre[64728]
"

I restarted the app and connected successfully. We shall see what the new year brings. Might be time to convert the Mac Mini to Ubuntu.
