TAG NAME shutdown_lifetime
Description This is the time Squid allows for existing connections to continue after it has received a shutdown signal
Build Option
 Default
Usage
 shutdown_lifetime time-units
Default
 shutdown_lifetime 30 seconds


Synopsis
When SIGTERM or SIGHUP is received, the cache is put into “shutdown pending” mode until all active sockets are closed. It will stop accepting new connections immediately, but connections already in progress will continue to be served for this amount of time. Defaults to 30 seconds, which is a good safe value. Any active clients after this many seconds will receive a “timeout” message.

Note: If this time is set to be too low then some file descriptors may remain open which will be a performance issue in memory usage.

Arguments

time-units
 Time period of “shutdown pending” mode

Example(s)
