It didn't seem attributable to a certain batch or physical location. The uptime was not collected, but most were in the ballpark of 30-90 days. I was tailing /var/log/messages, but didn't save kern.msgbuf no. I've added both of these to the collections and pulled a couple that did fail more than once and will be re enabling MSI-X on them later today.
