Good morning Robert. There was a round of kernel upgrades recently to address several issues, as well as to prepare for our upcoming release of features for the QCP. http://forums.quantact.com/showthread.php?t=972 Your vm was migrated over to vz11 this week to address the kernel issues in the above link. Host vz11 was rebooted this morning to address a high load condition, so you experienced an unscheduled reboot for your vm. Let us know if you have any questions.
