"Error" When I Cleared Cache

[monicakm]

I turned off my phone-press and held the power button, home key and volume up till the phone did a short vibration and entered into Recovery Mode.
Selected wipe cache partition. The little triage Android had the words "no command" at first and after I wiped the cache and pressed the start key, the word "error" appeared under the triage Android and the phone continued to reboot. What happened?

I see this mentioned sometimes, and have yet to find a clear answer. I'll be interested to see if anyone has insight into it, especially since I end up recommending cache partition wipes so often!
