Besides restarting tasks from scratch, I also noticed that the app sometimes keeps computing for a couple of dozens of minutes but the progress is stuck with like 2%. So I cleared app data, logged in again and voila, everything suddenly works fine. I wonder if this is some memory leak or silent data corruption or something. I do think it is app related, not project related.

Thank you guys for your reply.

@Raistmer: See, Android client sometimes gets suspended when I turn the screen on for no reason. It says it is running on batteries but it is of course not true. It takes it a few seconds to resume calculations.

@Dave: Checkpoints came to my mind, too but I'm afraid similar tasks from the same batch ran, got suspended and resumed again without any problem. What I noticed however is that Rosetta@Home is very RAM consuming (i.e. 1.7 GB or so). I sometimes saw warnings in the Projects section that the available memory was insufficient even after reboot of the phone which is very weird. This wouldn't stop BOINC from downloading and running tasks in a while, though.

I have noticed weird behavior of BOINC client for Android which I use for Rosetta@Home project. What happens is the client works fine for several days / weeks but suddenly, it cannot complete any tasks as it keeps restarting them every time I have a look at the UI. Restarting the phone or clearing the cache of the app does not help. What worked for me earlier was to remove all app data and add the project again but that generates a new ID for this phone and I lose progress of the running tasks which sucks. Any ideas?

Here is the log from today morning after I restarted the phone. It's Huawei P20.
