timer based rez object script stops on logoff or leaving sim

This is driving me insane... one of my gadgets that I created periodically rezs an object, which has a life span, then dies, then it rezs another.... so it can only have say, 5, at a time. Up until about a month ago I had no problems... now, they stop for 'no reason'.

Here's what I've found:
If I stay on the same sim as the rezzer, it keeps working. for a lllloooonnng time. If I leave the sim for more than a few minutes or log off, it stops. The script appears to be in the same state that is was, however the rezzed objects have all died, and no new ones are being rezzed.

Has anybody else encountered this, and the better question, why is it happening, and what can be done about it?

Thank you for the link... absolutely ridiculous that this has gone on for this long.

Is this fixed if the object is set to group, or deeded to group?
