Build failed: API error (500)
Some times in shared runners on gitlab.com happend error:
ERROR: Build failed: API error (500): Cannot start container 258bfeb566eda73d7f0a00ef8f6ddd5770e7e9a1f95a490145d8069b204e3d5b: [8] System error: read parent: connection reset by peer
Probably it can be reproduce if many builds already running
