Hello, We have a mult dc zk cluster, and all of a sudden we started seeing timeouts with observers. while we are investigating the possible network issue, we would like to understand accepted values for ticket time and synclimit? The time out is syncLimit * tickTime currently we have it set to 2 * 60000 = 2 minutes. we would like to increase the value to 6 minutes. what is the impact of increasing it? what are the acceptable limits? Thank you
