Hi Everyone, There is no limit for the value of inter parameter. Same query was asked in the community :- https://discourse.haproxy.org/t/maximum-value-for-inter-parameter/2142
Here, I have created a patch (Version - 1.8.1) for limiting the maximum value of "inter" parameter. As currently, no parsing error is displayed when larger value is given to "inter" parameter in config file. After applying this patch the maximum value of "inter" is set to 24h (i.e. 86400000 ms). If user enter any value > 24h then parsing error would be displayed. Please let me know if the patch is fine and can be merged to the main branch. Thanks Nikhil Kapoor

Description: inter_max_check.patch
Problem:- No parsing error is displayed when larger value is given to "inter"
parameter in config file.
A parsing error should be displayed on the screen.
Detailed steps:
1.Create 3 nodes setup(node1, node3 as backend servers, HAProxy is installed on
node2.
2.Set 'inter 10000000000'in haproxy.config
3.Start Haproxy (systemctl restart haproxy)and check status of haproxy
(#systemctl status haproxy)
When value of 'inter' parameter is "10000000000" in haproxy.cfg and haproxy
service is started, no parsing error is displayed.
Solution:-
A check has been extended in parse_server() of server.c file, to verify the
parameter value and display the parsing error if a value is greater than
24h(86400000 ms) process termination.
< /* The value of 'inter' parameter cannot be
greater than 24 hours */
< if (val <= 0 || val >86400000) {
---
> if (val <= 0 ) {
