On 2/19 I installed RU4 for Exchange 2010 SP3 on a server at a client's site. This is a single server with all the roles on it, with about 40-45 mailboxes. Ever since then, during the busiest hours of the day (around 7AM to 5:30PM or so), I get the following event log error on this server:

The frequency of these errors varies and it definitely seems to be related to the amount of traffic. Over the weekend it only occured about 5-10 times a day. For the past couple of days, it's been pretty constant about every 15 minutes or so all day.
I've looked this up, but I've only found a few posts mentioning similar errors, all relating to earlier versions of Exchange 2010. Supposedly this problem was fixed in one of the rollups to SP1 or SP2, I think. I never saw these errors, though, until the SP3 RU4 rollup. I haven't heard any complaints from users, but I'm concerned that this might escalate and start causing noticeable searching issues.
Any ideas would be appreciated.
