At 20:50 CEST we received our first alert regarding a hypervisor being unreachable. Upon investigation we found that the nf\_conntrack table was full. We're still investigating what the reason for this is since we have a fairly high value for nf\_conntrack\_max, and nf\_conntrack\_count is nowhere near the value of nf\_conntrack\_max. We have increased (3x) nf\_conntrack\_max and rebooted the server. At 21:31 CEST the server was rebooted and all VM's were being started..
