Same error filling my log

[TheeGrizzly]

I’m running fog .32 on an ubuntu server.

when i vew my log viewer it is filled with error that state "
[06-21-13 8:13:41 am] | [06-21-13 8:13:41 am] Failed to connect to database server, will try again in next iteration."

Really have no clue what causes this or how to fix it.

Any help would be great
