Hi, At about 19:30Z we started receiving alerts for customer services on server "limoncello". On investigation it quickly became apparent that this was the intermittent "I/O stall" problem we've been seeing on all servers and have been grappling with for months now. All I could do was power cycle the server. My current line of investigation is to upgrade both the hypervisor and the kernel when this happens, and so far it hasn't reoccurred on any of the servers where that has been done, though the sometimes months long gap between incidents means it's not possible to be sure. Although this last happened 16 days ago, that was on a different server ("jack"). With the upgrades done the server was rebooted again and at about 20:28Z customer VMs started booting again. This was complete by about 20:45Z.
