Hi Alex, as a beginning can you move the recycle optimizer *before* GarbageCollector in the optimizer list? The recycler is designed to collect intermediates before they are garbage-collected. As Martin said it is an experimental code and they might be other pitfalls, esp. under Windows. Please, keep us informed. Regards, Milena

Hi,
I have a query that runs without any problems when the default optimizer settings are used. But once I add 'recycle' to the existing optimizer modules, the query doesn't return. Mserver seems to be stuck in an infinite loop with 50% CPU usage

preferably by filing a bug report via https://sourceforge.net/tracker/?atid=482468&group_id=56967&func=browse
((for now?) the best way to keep us alert & reminded and to trace the progress ...)

I am running Monet compiled from CVS on Windows.
This is the query:
select sum(t1."AddressID"), "hour"(t1."ModifiedDate") as aa from "schema1"."CustomerAddress" as t1 inner join
"schema1"."CustomerAddress"as
t2 on t1."CustomerID" = t2."CustomerID" group by aa
This is what I get from 'select opimizer':
inline,remap,evaluate,costModel,coercions,emptySet,mitosis,aliases,mergetable,deadcode,constants,commonTerms,joinPath,deadcode,reduce,garbageCollector,dataflow,history,multiplex,recycle
Thanks.
