Hi @iovcho 👋

The 108 bytes limit is set by Linux, so unfortunately there is not much we can do about it. The socket is placed inside the task directory, so maybe you can try a shorter task name?

Another thing we noticed is that the task name in your sample job file is job-test, which should leave plenty of room for the full socket path. Was this the task name you were using when you receive this error message?

To help a bit with problems like this I reduced the socket file name in In #13971 to give some characters back to other components of the path.

Hello from the future 👋

I cleaning up some stale issue and we haven't had any updates on this one for a while, so I'm going to close it for now. But let me know if this is still a problem and we can reopen it.

Thank you!
