Error while running the VMR using docker on Ubuntu 18
Hi,
I am facing this issue while starting up the VMR on Ubuntu 18.
Has anyone faced and fixed this issue?
Starting VMR Docker Container: Wed Oct 9 06:48:32 UTC 2019
SolOS Version: soltr_9.3.0.22
ssh-keygen: generating new host keys: RSA1 RSA DSA ECDSA ED25519
** Unable to raise event; rc(would block)**

Thanks for the info.
The second "docker ps -a" shows that the docker container started 15 minutes before, and exited 4 minutes before the docker ps command, with exit status 2. Exit status 2 is a general purpose error code for our product.
Please run the following to retrieve the shutdown message from the container:docker cp solace:/var/lib/solace/diags/shutdownMessage .
Please run the following to get another log file:
docker cp solace:/usr/sw/loads/currentload/.lastRespawnsAction .
Please return those files. Thanks!
Because you are running Ubuntu, with AppArmor, try adding the following to the
docker runcommand, to give your container more privileges--security-opt apparmor:unconfined
Some errors related to Solace are generated by the Linux kernel in the regular log files in
/var/log. Look for things that happen at the time of the exit, approximately.
Examples:/var/log/syslog- general errors/var/log/kern.log- various kernel errors, including Out Of Memory (OOMkills) where the kernel killed the process, rather than something inside the container if it ran out of memory.
Some processes that run in our container, and might show up in log files, are:
- multipathd
- solsyslogtee
- solacedaemon
- watchdog
- dataplane
- controlplane
- smrp
- trmmanager
- msgbusadapter
- solcachemgr
Of course 10-50 lines of context before and after is always helpful.
We aren't sure what specific errors to look for here, sorry. However, those logs should help.6

Thanks for asking.
I am checking with some people with experience in this area.0 -
Are you installing a Docker image directly, the QCOW image, the OVA image, or something else?
Also, if you have a longer log file of the output, please attach it as a file.0 -
I am told that "Unable to raise event; rc(would block)" is an error message from something that runs in the startup phase before it is ready. It is run again later, so that error does not indicate a problem.
Can you please post, preferably as an attached file:
- The output of:
docker ps - The output of:
docker inspect (container name) - The output of:
docker logs (container name) - The actual command line you used to create the container, if you have it.
Thanks!

This one made the trick: --security-opt apparmor:unconfined
Thanks a lot0 -
Hi Thierry,
Happy to help.
We have a bug to fix some things in those docs, and this info for Ubuntu will go in there.
Thanks for letting us know. And I think I will ask IT for an extra machine with Ubuntu on it. (grin)0 -
Actually, kudos to the team in Solace Singapore!
