Similar problem & similar solution required under intense batch processing, but not for individual runs. Like you I dont understand it. But would like to. Appears that perl's inbuilt self-cleanup utilities (garbage collection etc) may need free time or free cycles or free cpu capacity to function properly, and otherwise unexpected resource usage aggregates until the system busts? Or something like that? When it occurs I have observed that cpu usage is 100% and memory usage often close to that, and I get a "Segmentation Fault" rather than an explicit "Out of Memory". Interesting find.
