Subject: timeout values for redis? 



Does anyone have any feedback on sane timeout values for load balancing redis? 

The testing config I was using had ‘timeout client 50000’ and I was getting 
consistent client disconnects in the logs. I increased it to two minutes and 
things have improved significantly, though I do see client disconnects every 
few hours (but the application is behaving normally). Client is 
StackExchange.Redis if that helps. 

Google wasn’t much use. HA-Proxy version 1.5.10. Full config: 


global 
log /dev/log local0 
log /dev/log local1 notice 
chroot /var/lib/haproxy 
stats socket /run/haproxy/admin.sock mode 660 level admin 
stats timeout 30s 
user haproxy 
group haproxy 
daemon 

defaults 
log global 
mode tcp 
option tcplog 
option dontlognull 
timeout connect 5000 
timeout client 2m 
timeout server 120000 
errorfile 400 /etc/haproxy/errors/400.http
