I've been having trouble with a patch locking up puredyne after 2 hours.

in the task manager the memory usage of pd-extended is gradually climbing, 1MB every 10 seconds.

Ive traced the problem to an subpatch that contains 350 tables. These tables are drum hit samples.

when I delete the tables the memory usage stops climbing. Looks like a memory leak type thing.

I'm using soundfiler to write the tables, sometimes when i search for last error the soundfiler is highlighted.

turned out the tables weren't the problem.

I traced the leak to the [mixer~] abstraction, not sure where its from.

I replaced these with home made mixer subpatch, Bingo!
