Process Lasso 3.60 x64 problem

[af4t]

I am running 3.60.5 x64 on Vista Ultimate (x64) .... which regularly pops up a message saying that the Process Lasso Core Engine has stopped working, with these details:

I will get this message usually within the first minute after system start, then again periodically after restarting the governor with the tray icon.  It has been seeming to mitigate the problem if I import the digital signature certificate for processgovernor.exe, but this doesn't ever last past rebooting.

There are usually two users logged into the system, but this doesn't seem to make a difference, it happens with only one (myself) logged in also.  It happens with processgovernor.exe having normal rights, highest rights, or installed as a system service, I have tried all three options.

Vista Ultimate x64 is installed as a dual boot system with Vista Home Premium x32 ... I never have this issue with the 32-bit OS.

Wish I had more technical expertise to give you additional details ....

Any ideas how to stop this annoying behavior?

Thanks

Thank you for reporting this anomaly. I am very concerned about it, as a crash like this is surely affecting other users. My primary development system is now running an x64 OS, so the x64 build does get pretty well tested (as does the x32 build). I need to find out what is different on your system than in my test beds. The crash may be some timing issue, but this seems less likely as I'd surely have seen it myself at least once, and you would surely not see it so frequently.

Can you please post your configuration file and log? Alternatively, you can email them to jeremy@bitsum.com. The path to them is listed in the about box. This may give me some clue as to what is going on.

Thanks again for the report, and I appreciate any time you're able to give in helping track down the cause.

Thanks!

I will let it happen a few more times to gather evidence for you.

It did happen twice last night, I did not have system services excluded from Pro Balance and the crash happened right after adjustments to svchost.exe ... now have system services excluded from Pro Balance to see what happens.

Great, I appreciate your willingness to help investigate. Please keep me updated.

For readers: This problem was tracked down to customized CPU Throttling on an application. A fix is still pending, but this errata should not affect many users at all.
