reading ultravnc.ini indefinitely

[mike796]

I used filemon to monitor my hard drive activity.
I noticed that the ultravnc.ini file is red every 5 seconds.
That is slowing down my system.

So the following sequence repeats forever:

Is it a bug or a feature ?

I don't know, but I find it kind of funny that it can do that every 5 seconds but <b>never</b> checks for new local NIC card IP addresses to bind to.

[mike796]

At least somebody can confirm this behavior on his PC, Please ? At least I just want to know whether it is only a problem with my PC ?

You can check with process monitor or Filemon:

Filemon:
http://en.utilidades-utiles.com/downloa ... ows-xp.php

Process monitor :
http://technet.microsoft.com/en-us/sysi ... 96645.aspx

I can see in the log RANGE NOT LOCKED errors.
No idea what is the meaning.

Thank you

[YY]

I can repeat exactly the same result.

During this process, I even try to:

1. Change the password -- I edit the ultravnc.ini directly
　However, the Ultravnv server not implementing the change I made, working as before, but keep on reading the ultravnc.ini every 5 seconds.

2. Delete the ultravnc.ini
　The Filemon reflects the Ultravnv server realizing this fact, and reporting "Not Found". Again, the Ultravnv server still working normally but keep on trying to read the ultravnc.ini every 5 seconds.

Your discovery is really interesting!

Every 5 seconds there is a timer that update the tray icon.

Possible some parameter is read from the ini file, normal this shouldn't be needed... and cached value should be used.

[mike796]

Thank you all for your answers.
Actually, this is prevently my hard-drive to spin down when PC is idle (most f the time when I not home), and makes unexpected accesses to the disk which are interrupting other reading tasks.
Should I submit this to some "requests/bugs" section of the forum ?
Again thank you for having checked this issue with me.

[B]

Really? It spins up the drive instead of reading ultravnc.ini from disk cache? That stinks. I guess you could always run the whole thing from a virtual RAMDisk or something.

To me this does sound like something that should be addressed in the long term. (What if, for example, the drive that started WinVNC is removable; will a running WinVNC crash when that drive is eventually removed?)

You've got Rudi's attention, so that's a good thing. Honestly I'm not sure whether you're supposed to post in Requests/Bugs too, but I guess it couldn't hurt.
