Yes, we saw this at UC Berkeley. We could not identify the cause, and
the only solution was to restart Matterhorn on the agent.
I ticketed this issue in April:

Hi Stephen,
I remember that there was talk about the exact same issue about a year ago. You
should still be able to find something in the archives. As far as I remember,
it was UC Berkeley who encountered the issue back then.

Hi all,
Recently we came across an issue on 3 of our capture agents where the
load average climbed over time, eventually causing a capture failure on
one agent.
The details are reported here:
https://opencast.jira.com/browse/MH-9234. Unfortunately we ran
into a dead-end trying to identify the cause, as we were unable to get a
stack trace for the threads causing the load, although we did identify
that they were engaged in some type of polling of /dev/video0, an
Epiphan VGA2USB device.
Has anyone seen anything similar?
Regards
Stephen
