CONFIG_SHELL_BACKEND_SERIAL_LOG_MESSAGE_QUEUE_SIZE

Log message queue size

Type: int

Help

Amount of messages that can enqueued in order to be processed by shell
thread. Too small queue may lead to logger thread being blocked
(see $(module)_LOG_MESSAGE_QUEUE_TIMEOUT). Too big queue on relatively
slow shell transport may lead to situation where logs are dropped
because all log messages are enqueued.
