Hi All
Hoping someone will be able to help, we’re running a bit of an interesting setup
we have 3 HAProxy nodes running freebsd 11.0 , each host runs 4 jails running haproxy, but only one of the jails is under any real load
we use CARP to balance between the hosts and jails which seems to be working fine
about 1 once every 2/3 months, all the haproxy instances hang, the process keeps running, but doesn’t access any more connections, the monitoring socket is unresponsive. it doesn’t produce any errors in logs.
these hangs all happen within a couple of seconds, over all jails on all hosts taking down our frontend network, a restart of the haproxy service fixes it.
we use chef for config management, and all the run times are splayed, all the haproxy instances will have different up times
Any one who has an good idea of what could cause this?
Thanks!!
