High await (iostat) on not loaded system
Posted: Fri Mar 23, 2012 12:24 pmHello,
Often this message appears at random agents:
mtop says that's no slow queries but iostat, await column is strange:
await is always close to 300 and it's no matter whether the system is loaded with or without agents.

I think there may be a problem with hard drive. What do you think?
