This would indicate that too much audio was in flight to the output, if
it was running ok for some time then this probably means that the system
became very busy preventing the runner from freeing up these buffers.

I would expect one of these, receiving several of these is odd, I'll
look into it.

it will do if the timer is out of sync by about 40+ seconds,

use the -f flag as well to ps, that will tell me which thread it is. But
from those figures 10087 is the runner and the CPU is being spent doing
the re-encoding, if you want to avoid re-encoding use (within the
instance).

<passthru>1</passthru>

depending on the hardware ~35% CPU is not unreasonable for re-encoding,
but it seems the timer is way out of sync.  Do you have realtime
enabled?, it would say it at the start of the log before any processing
is done.
