hi!
(appologies for the length of this!)
we're doing more load testing on our 1.3.1 distributed matterhorn
install and ran into some problems with scheduled recordings the weekend.
most of our testing has so far been short ad-hoc recordings (our initial
deployment will be ad-hoc only) but we scheduled a bunch of recordings
over the weekend to stress the core a bit. recordings were between 60
and 90 minutes long and were recorded on an epiphan capture device with
the output from a PC showing a looped powerpoint automatically advancing
every 15 seconds, a camcorder and some music.
on checking this morning none of the recordings had made it through. the
first one (18:00 on friday for 1 hour) got as far as
'distribute-download' ok, but failed on 'distribute-streaming' showing
the following in the admin interface:
org.opencastproject.workflow.api.WorkflowOperationException:
org.opencastproject.distribution.api.DistributionException: Unable to
distribute mediapackage attachment-190 using a remote distribution
service proxy.,
org.opencastproject.workflow.api.WorkflowOperationException:
org.opencastproject.distribution.api.DistributionException: Unable to
distribute mediapackage attachment-190 using a remote distribution

org.opencastproject.mediapackage.MediaPackageException: Can not store
xacml for mediapackage bf603010-57d8-40e3-8c63-014719af113e
we have about 300GB free on the work drive, 5GB free in the root volume
and 2.3TB in our distribution volume so i assume space isn't an issue.
in the log on our admin node there is the following:

so i am guessing that the huge number of segments caused by the auto
powerpoint is not helping? (i'm guessing that's also why it took 5.5
hours to get that far!) it complains about the size of the POST to
http://matterhorn-worker.uscs.susx.ac.uk/distribution/streaming but I
can find no corresponding entry in the worker log - is that normal?
should we increase the allowed POST size (if so how)? it seems to us
that if there really are that many segments the engage player would
probably become unusable anyway - would it be possible to skip the
segmenting if the 'segment-video' job finds over a certain number of
segments perhaps?
the other thing is that none of the other recordings processed either.
most of them got as far as 'inspect' and then went into the PAUSED
state, but two of them got stuck before that saying 'Captured : Sending
recording to processing'. I resumed one of the PAUSED ones using the
workflow API but assume it will fail in a few hours time. resuming one
of the 'Captured' ones resulted in it saying 'FINISHED' but the workflow
had nothing added beyond 'ingest'.
i've since uploaded a file and it went through with no problem (while
the resumed one was still going too). does anyone have any idea why the
other scheduled recordings went into a paused state? (there is no
holding for trim or anything in the workflow)
i'd appreciate any light anyone can shed on any of this!
if more logs would be helpful let me know and i'll upload them somewhere.
just noticed there also appear to be some of these entries in the admin
log normally just after starting an encoding job:
