Workers failing

[davidediruscio]

Two of the 4 slaves have stopped last night. The UI doesn't show any worker or tasks or projects.

Log of the 2 stopped docker containers (oss-app slaves):

• oss_app_1.log
• oss_app_slave_1.log

The ci4 host (and portainer instance) can be freely investigated if needed. As a reminder, all URLs are provided in the main page:

The logs show that both JVMs have crashed due to SIGBUS (0x7), which is most likely a consequence of running out of disk space. Indeed, here's the situation in the container:

I am not familiar with Docker's volume management. Maybe there is a way to allocate more space to the metric-plaform containers (master and slave)?

Humm, it really seems to be the case that the Docker container ran out of storage space. I will look into it.
