Hello,

we are running the 26028 version of the vboxwrapper for some time now
and I want to update you on some ongoing problems.

Some users reported that the stderr.txt is filled with lots of error
messages and file size increases to several GB. The file was truncated
by the user and I didn't see any unusual disk_size_limit_reached errors.
So either this was an isolated incident or the file size doesn't matter.

Many users reported that the VM is still running after the BOINC Client
was shut down. Lammert van der Veen did some research to the cause and I
hope this can be fixed by limiting one concurrent VM per Host and the
26031 wrapper as soon as I upgrade our application.

Trickle messages were working fine when running with short tasks. Now
that we have some longer tasks the trickle up messages stopped. We
didn't receive any in over a month. I think I have an explanation for this:
In the vboxwrapper the trickles are generated every X seconds cpu_time
and not wall_clock_time and as the vboxwrapper is not doing much the
cpu_time increases very slowly. What I want is a trickle message every X
hours of VM runtime! Please look into this asap because without this
feature I have to monitor the deadlines and extend them by hand.
If it may be helpful:
A recent long running task reported back with cpu_time=793517.4 and
elapsed_time=839064.946827 but I also have a task with cpu_time=4280.246
and elapsed_time=378984.324896 I can't see any trickle messages for both
of them.
first: http://www.rnaworld.de/rnaworld/result.php?resultid=14920843 (Job
Duration is always 0, Elapsed time is increasing)
second: http://www.rnaworld.de/rnaworld/result.php?resultid=14921349
(can't see anything in stderr)

Speaking of deadlines, it would also be great to update the deadline on
the client. I know of one user who updates his client_state.xml by hand
to prevent the Client from going into high priority mode for RNAWorld
when there is no need.

Regards
Christian
