I am finding that the latest build leaks an enourmous amount of Win32 handles. The vast majority of windows applications and services use, at most, around 200 handles whereas PWS will use upwards of 85,000 or more! This is all coming from the Parallel Tools executable. Below is a dump from TaskInfo which clearly shows the extent of the problem. CMD = "C:\Program Files\Parallels\Parallels Tools\ParallelsToolsCenter.exe" Curr Dir = C:\Documents and Settings\jdoe\ Path = C:\Program Files\Parallels\Parallels Tools\ParallelsToolsCenter.exe User Name = MACBOOK-PRO-XP \ jdoe PID/Parent PID = 2536 / 1788 Started by = C:\WINDOWS\Explorer.EXE Virtual KB Curr = 58,192 Peak = 69,436 Working Set KB Curr = 12,840 Peak = 18,956 Page File KB Curr = 9,036 Peak = 15,116 System Pool KB Paged = 629 Nonpaged = 5 Private KB = 9,036 Handles Count = 74,679 Faults Count = 10,940 Objects = USER = 174 GDI = 121 Windows = 157 Reads = 193 Read KB = 65 Writes = 13 Write KB = 21 Other IOs = 412,827 Other KB = 535,890 In the time it took to write this post, with nothing running in Windows and the Win OS basically idle, the handle count has increase to 83,920 from the 74,679 it started at just a few minutes before. The CPU is working at an average of 20-30% to keep up with the idle process. What can be done about this if anything?
