Hi all,

since the upgrade from Opencast 10.09 to 10.10 (as far as i can see), the following error appears in the log after a restart of the opencast service:


" org.osgi.framework.ServiceException: Service factory exception: Could not obtain lock"

Any hints, what is going wrong?

Thanks in advance

Stephan

Hi Stephen,

How are you upgrading? Do you somehow have two copies of Opencast installed at once? I don't recall seeing that kind of locking error before.

Hi Greg,

It is a multi node setup. 

1x admin
1x presentation 
12x worker

Every Node is connected via IPv6 and the Upgrade was made via rpm packages (CentOS 7).

If u need more Information, let me know.

Hi Greg, Hi all,

Hi all,

the problem is still there - but after some restarts of the Opencast service, the errors are gone. Any hints, what can cause these errors?

Regards

Stephan

Hi Stephan,

How many tenants do you have?  Are you by any chance running with multiple?  No idea what's going on, but that LTI-related stack trace you posted isn't something I've seen before.

Hi Greg,

it's only one OC 10.11 tenant. There are no other instances of OC running. I don't get why it sometimes fails and sometimes it's need a lot of time (over 10 Minutes) to be ready, Maybe the virtual machine for the admin node is undersized for ~75000 Videos?

14 vCPUs
32 GB vRAM

Hi Rainer,

one of our clients had issues after a Java update that was fixed with a restart of the opencast service, maybe this was your problem as well?

Cheers,

Hi Katrin,
we tried to turn it off and on again ;-)

Just a wild guess: Looks like the presentation does not like it if a database dump is being made in parallel.

We haven't updated Java but I moved the cronjob to restart the presentation server one hour back (so it would affect less people) but have forgotten that the database dump would be still in progress at this time.

Apparently, the connection test from the docker container to the database succeeds but MariaDB and our admin might not respond to relevant queries for some time due to tables being locked.

Ah yeah, that could do it.

Well you never know. ^^' Glad to hear you found it though.
