I've never heard of that one before. But I'm a pretty simply guy that doesn't run a lot of stuff that syncs, mostly just email. Is it possible its an app that is trying to sync? You could try freezing those so they don't run for a while, check your settings/accounts, especially the Google one and uncheck anything in there you don't need to sync like Picasa for example.
Plus its might be hard for you to track down if its pretty intermittent.
