Answer
JSON logs fill writable layers, consuming disk and freezing hosts.
Quick Answer
Docker log drivers collect container stdout/stderr and forward them to logging backends (journald, syslog, fluentd, splunk). Some drivers buffer in kernel space. If the logging backend is slow or down, the kernel buffer fills, causing backpressure that blocks container writes to stdout — eventually blocking the container's app process.
