Sorrry...but.. no news about the memory bug? I remember you that after some test, the first version that work fine on my vps is the 187 (with RAWR template 0.1.1 without delete).
The bug can be easily reproducible, simply leave the program run for some days, then download a file (in my case from 300 to 4000 M) with a dl accelerator (i use downthemall in firefox) and/or more then one file.
The memory size of HFS, mesured with Task Manager, grow to full the memory (> 500M, then the system hangs....).
I hope this is usefull, for more info e/o test.... i'm here!
