server-lifetime
Some systems have problems with resource leaks (memory, file descriptor).
To get around this, the child processes die after a certain period and
are reborn. Set server-lifetime to the number of minutes a child
will wait around for before dying. Note that a child may live longer than
that if it is servicing a user, since it doesn't prematurely end a user
session. Don't set it too low or else the child wont be able take
advantage of its caches, which are re-learned each time a child is born.
Examples:
server-lifetime=120
server-lifetime=720
