Array threw error FLARE_CPU_WATCHDOG: BackToHostside not rescheduling

Good morning, all! One of my VNX5300 arrays threw an error early today: FLARE_CPU_WATCHDOG: BackToHostside not rescheduling. Googling this error didn't show a cause or a fix. Pretty much what I got is it's either transient or the CPU is about to panic and shut the whole array down mid-stream. I did look at the VMware hosts that use this array, and there was some sustained latency on one of the hosts that stopped about the time the warning was generated. Any thoughts on what might be going on? Thank to all for looking! Gregg
