Fix random connection timeouts with Redis Cluster

kjoe · michael-grunder · commit eb7f31e7affd · 2024-03-25T12:04:06.000-07:00
When a node timeout occurs, then phpredis will try to connect to another node, whose answer probably will be MOVED redirect. After this we need more time to accomplish the redirection, otherwise we get "Timed out attempting to find data in the correct node" error message. Fixes #795 #888 #1142 #1385 #1633 #1707 #1811 #2407
