Hello,
I have a cluster of 3 haproxy nodes in All-Active mode using Pacemaker and corosync. OS: Ubuntu 12.04.5 Haproxy - 1.5.9 nbproc 16 This cluster works ok in general. The issue: If the backend servers are responding slowly for some reason, all haproxy nodes will crash. i configured queue to 1 and set up reasonable server and client timeouts on haproxy however if for some reason connections builds up on haproxy crashes and the machine becomes unresponsive (all haproxy nodes) I don't see any kernel errors. 1. how can i debug this ? 2. what is the best practice to protect haproxy from such situation ? Thanks Haim Ari / SysOps Manager M: 972.584563032 / T: 972.722288367 [Meet Us at] <http://www.startapp.com/press/#events_press>
