Subject: [PATCH] revert serverside behavior of keepalives
|
|
|
|
This patch intends to bump up the time that a client has to reply to the
|
|
server back to 30 seconds as per pre 1.12.2, which allowed clients
|
|
more than enough time to reply potentially allowing them to be less
|
|
tempermental due to lag spikes on the network thread, e.g. that caused
|
|
by plugins that are interacting with netty.
|
|
|
|
We also add a system property to allow people to tweak how long the server
|
|
will wait for a reply. There is a compromise here between lower and higher
|
|
values, lower values will mean that dead connections can be closed sooner,
|
|
whereas higher values will make this less sensitive to issues such as spikes
|
|
from networking or during connections flood of chunk packets on slower clients,
|
|
at the cost of dead connections being kept open for longer.
