When expire_nodest_conn=1 and a destination is deleted, IPVS does not expire the existing connections until the next matching incoming packet. If there are many connection entries from a single client to a single destination, many packets may get dropped before all the connections are expired (more likely with lots of UDP traffic). An optimization can be made where upon deletion of a destination, IPVS queues up delayed work to immediately expire any connections with a deleted destination. This ensures any reused source ports from a client (within the IPVS timeouts) are scheduled to new real servers instead of silently dropped.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
