Task has been rescheduled

I have lots of these messages in my altiris logs:

AeXMetricProv.exe

[WAR] CScheduler::WorkerFunction() task has been rescheduled, it still running, CSchedObj<0x0000000000BA6C90 interval=60000, timeout=4000, prev=2013-07-18 14:20:15, next=2013-07-18 14:21:17, stagger=0, active=1, latency=High>

How can I hunt down the task and clean them up?
