watchdog

watchdog

Threaded server watchdog. Optional, default is 1 (watchdog enabled). Introduced in version 2.0.1-beta.

A crashed query in threads multi-processing mode (workers = threads) can take down the entire server. With watchdog feature enabled, searchd additionally keeps a separate lightweight process that monitors the main server process, and automatically restarts the latter in case of abnormal termination. Watchdog is enabled by default.

Example:

watchdog = 0 # disable watchdog
