Hello,

the relevant logs are:

lava-dispatcher    | 2020-01-20 20:03:50,031    INFO [4284] Job END
lava-dispatcher    | 2020-01-20 20:03:50,031   ERROR [4284] Unable to read 'description.yaml'

lava-dispatcher    | 2020-01-20 20:03:50,034   ERROR [4284] lava-run crashed

The main problem is that we don't see anything in this log.

Could you provide the job logs?

Hi Remi,

 

For more information, I have followed https://collaborate.linaro.org/pages/viewpage.action?pageId=118293253 which uses a docker-compose setup from https://github.com/Linaro/lite-lava-docker-compose

 

Below pastebin has all docker-compose logs for recent lava-run crash (job 4284) using 2019.12 images.

Thanks,

Alex

If you use the lava-dispatcher docker container, then the lava-slve logs are printed on stdout. So "docker logs" would give you the logs.

In my lava-dispatcher docker container, /var/log/lava-dispatcher/ exists but is empty.

 

Thanks,

On the dispatcher, look for /var/log/lava-dispatcher/lava-slave.log

Hi Remi,

 

The log states “lava-run crashed”, I don’t think there is any lava-master crash because lava-master continues working fine for subsequent jobs. How can I get the lava-slave logs to check for a crash there?

 

Thanks,

Alex

Hello,

 

this is lava-master crashing, not lava-run right ?

If lava-run is crashing, please provide the corresponding lava-slave logs.

Hello,

 

Our internal LAVA setup has been hitting this crash intermittently (it reproduces about one out of every 30 job submissions). The below log snippet is from the 2019.07 LAVA docker images, but we updated to the 2019.12 images and the crash still occurs with the same error signature.

Please let me know if I can provide any other info to help debug.
