Defraggler: Willy2's bug reports in Defraggler Bug Reporting Posted June 26, 2020 - Have been using DF today again and when I opened RAMMAP I saw 43 DF "Zombie" processes ("Defraggler.exe") while Task Manager showed only one process called "Defraggler64.exe". - It seems that somehow the process "Defraggler64.exe" opens "Defraggler.exe" and uses some of the subroutines and then "forgets" to tell the Operating System that the process has done its job and the process can be "closed"/"removed". - This also can be a bug in the program code. E.g. "Defraggler64.exe" has all the subroutines it needs to perform its tasks but still calls upon "Defraggler.exe" every now and then. This could be a remnant of a previous Defraggler version before there was no 64 bit version of the program. Lots of possibilities on why so many Zombie processes show up. - When I look at the size of the 43 DF "zombies" then I see that these Zombies actually don't use that much memory. RAMMAP reports that each of these 43 processes only use 20 Kb. Seems each of these processes are opened/created but then these processes each are hardly used/don't see little or no "activity". And - in general - one can say that the more a process is being used the larger the memory footprint. There the low memory usage could give a good indication of what's going on. - Another thing I noticed is that as soon as I close DF the zombie processes (seem to) disappear away as well. Odd, very odd.
