Message 1846 - Posted: 4 Feb 2016, 10:54:08 UTC - in response to Message 1758.  

The graceful shutdown of VMs has now been implemented. When the VM is older than 24 hours,
after the current run has finished the VM will shut itself down using the completion_trigger_file method.

It's not working as expected.

Run 4 ended after 27 hours and 50 minutes elapsed time and 25 hours and 12 minutes cpu time.

Me waiting for the shutdown, however:

Run 5 started and after 2 minutes
Run 6 started and after 2 minutes
Run 7 started and after 2 minutes
Run 8 started.

Enough waiting, so I shutdown the VM myself graceful with a trigger file.

The forced shutdown at 36 hours works.

Shame it had got as far as the 223rd record on the last job but hopefully it shouldn't usually run for that long.

The kill after 36 hours wallclock is just for when the graceful method did not work.
So far I did not notice the graceful shutdown myself, but appearently it's working for others:

How are you managing to get new jobs? I recently get the message that I need a huge amount of memory.

That were CMS-tasks from the VirtualLHC@home project using the same VM and software.
A few hundreds of CMS-tasks were submitted over there yesterday and quickly gone.

It is actually disk space.

Server is messed up.
