What causes these errors?

My android was doing cartwheels the other night, it was running extremely slow.
When the last error. (last picture) Came up I had to pull the battery. I did a virus scan and nothing is lingering in my system. What makes this happen? It had happened twice. And every once and awhile I have these slow spells without any errors.

Android phones are basically mini computers and every now and then a process gets out of hand. A reboot usually clears that up. If it happens often, you might want to install an app like Watchdog Lite and monitor things for a while.
