MCM task is ready to start, but never starts

According to BOINCTUI my Samsung Android phone has a task that is in a state Wait that doesn't start:
Wait - World Community Grid 33h 99h 44h Mapping Cancer Markers - MCM1_0229522_2902_1
Both TUI and Manager are newly started, so the information comes from the phone. I also restarted the phone before starting TUI and Manager.

The phone also runs a non CPU intensive task: WUProp@Home, but even if I suspend that the WCG MCM task doesn't start.

I cannot get new tasks from other projects because:
Not requesting tasks: don't need (job cache full)

It seems that the WSG task that does never start blocks other tasks.

Then I aborted that task an a new WCG task was downloaded, but that also waits ready to start forever:

Re: MCM task is ready to start, but never starts

As I mentioned privately to mobluse, my guess is that some resource is low and it prevents the work unit from starting. I encountered this with Rosetta years ago.

I stumbled upon the option to control the types of messages in the Event Log.

In the Advanced View, choose Options > Event Log Options...

There are many options and I only have file_xfer, task, and sched_ops checked (enabled) on my system, which is likely the default.

Would enabling something like cpu_sched_status show additional message types related to a low resource?

Or is there another BOINC tool that might help?

Re: MCM task is ready to start, but never starts

I have noticed a similar problem on my Android phones. The message says "Computing will resume when battery charge charge reaches 25% (currently 91%)." Ive tried rebooting, pausing, resuming, fiddling with various settings, running the battery down and charging up again, but this bug persists across three different cellphones (1 Samsung 2 different Motorolas). Then sometimes they start computing - hours later - by themselves. Annoying bug!

Re: MCM task is ready to start, but never starts

Go to the Official BOINC Message forums, read through the topic from August of 2024
"App can run only when screen ison'" link >

There's some possible solutions / work arounds to the known battery issue which the BOINC Developers are aware of and currently don't have a known solution to.
