While reviewing the event logs on our SourceOne master server I discovered the following errors being logged in the EMC event log, several per minute. I don't see any failed jobs in the Job Management list. Does anyone have any ideas what is causing this? We currently use journaling, archiving and shortcutting tasks.

System call failed. (0x86040100) Invalid pointer  (0x80004003) [ExJobScheduler.exe, ExSchedulerThread.cpp(927).CExSchedulerThread::InsertJobForTask]
