wdqs1009 crashed around Feb 13 15:41:01. Syslog and System Event Log don't show anything obviously suspicious. @MoritzMuehlenhoff suggested updating the firmware, which might resolve the issue and would probably be the first step if we need to report this to the vendor.
@Cmjohnson The data reload is complete on wdqs1009, so the host can now have its firmware upgraded and be rebooted at its convenience. Note this is an internal wdqs test host, so there is no public-facing service for us to worry about.
Feel free to proceed when convenient for you - just shoot me a ping or drop a line in #wikimedia-discovery, but no need to schedule a formal window.
