2.2.0 throwing stack trace errors

[Jon Schneider]

2.2.0 on CentOS 6.2 x64

I have been seeing several instances of servers throwing the following messages to the system console over and over:

Anyone have an idea on what might be causing this?

Hi,

Would you mind posting the logs few line before?

[Jon Schneider]

Yea that's the strange part, there is nothing logged in the logs.  This message comes up on the system console.  I could enable a higher log level but its somewhat random and this is a prod system so I don't want to mess with it.  In some cases I have seen it pop up every few seconds, in other cases every few days.  It's not causing any problem that I can tell, just wanted to make note of it.
