ActivityScheduler thread error written to log file once a minute

[chris.valenti]

We are currently running Plastic 4.0.239.12 with a SQL Server 2008 R2 Express Edition backend on a Windows Server 2008 R2 VM. Ten minutes after starting the Plastic service, the ActivityScheduler starts writing an error to the Plastic server log file every minute, which grows the log quickly and makes it difficult to find anything inside. While we haven't seen any issues yet (users have had no problem checking files in/out, syncing, creating repositories, etc), I would like to know what's causing this message to be written so frequently and what I can do to stop it.

This is an excerpt of the log file from start-up of the Plastic service and a few of the ActivityScheduler messages:

Hi chris,

it's a warning message wrongly logged, it's fixed in the new .18 release (It's running test right now)

Keep tuned for the new release.
