|
Added a new haproxy configuration variable,
|
||
|
|
``haproxy_host_ipv4_tcp_retries2``,
|
||
|
|
which allows users to modify this kernel option.
|
||
|
|
This option sets maximum number of times a TCP packet is retransmitted
|
||
|
|
in established state before giving up. The default kernel value is 15,
|
||
|
|
which corresponds to a duration of approximately between 13 to 30
|
||
|
|
minutes, depending on the retransmission timeout. This variable can be used
|
||
|
|
to mitigate an issue with stuck connections in case of VIP failover,
|
||
|
|
see `bug 1917068 <https://bugs.launchpad.net/kolla-ansible/+bug/1917068>`__
