Re: Timeout during image build (task Networking)
Might be nice to figure out why the code to clean unused locks on worker startup is not working. It should detect orphaned locks and delete them but it sounds like it isn't working. Maybe because the pid has been reused by another process? Maybe we can improve it to make sure the process represented by the pid actually has the lockfile open with lsof?
