I haven't checked the links provided here yet for lack of time. I have run into this in the past. The error I was having was with pop and shift not releasing the memory on shared arrays.

For a quick fix I changed the dequeue method in Thread::Queue to do a: delete $q->[-1] (which returns the value deleted) instead of a shift. I also changed the enqueue to unshift instead of push to return it the correct behavior of a queue. This seems to work.

Not sure if this will help, or what the internal differences between a delete and shift would be to a shared array. Good Luck.

Edited: Ah there certainly is a patch, I could of used that few months ago. :(
