The stack table iirc is used to avoid scheduling the same tracks close 
to each other. You should be good to just prune it when it hits, say, 
8000 rows (enough for a month of fully automated play scheduled by 
rdlogmanger not to repeat). I don't think that Rivendell contains any 
logic to automatically do this for you, though. Might be worth filing a 
bug report in Mantis so this can get fixed, as it's clearly an issue.

Cheers,
James Harrison
