COM Surrogate Opens and Closes

The program makes a backing file with a .pml extension. You can stop the logging after a very short time and then save the log. Check it yourself to see if you notice anything, or we can talk about having it checked if you desire.

I am guessing it will only take about a minute or less to see what is going on. There are options on the top menu to see what is using the most CPU time or most number of entries.. Play with it for a while to see how it works.

I just ran mine and Dllhost.exe will show up as a PID (Process ID) so you have the name and PID number to search for. You can then just include the PID or name, and see just what it is doing. I would expect some action to repeat multiple times, and if you can find that, you might be able to tell what is causing it.

I will upload 3 pml files here. Could you check them? I don't know what I am looking for.
Sometimes the process keeps opening and closing, right now it is not doing that. Just opens once, then closes and that's it.

If we are talking about Photoviewer, the process should start and stay open while the photo is open. If it is not, possibly something is still wrong with your system files or something is interfering.

Check the file size before you upload, they can be quite large. My 1.5 second log was around 7 MB. Zipping it would help.

Sorry for late reply. Found out the cause of everything: LOOSE SATA CABLE. I replaced the cable since the old one had a bad design and it didn't have a tight fit.

Shortly after the last reply, my secondary hard drive, where I was having the problems, suddenly unmounted itself and kept doing this randomly after each reboot. Sometimes it would stay there for about an hour, sometimes a few days before it unmounted. I replaced the cable and I have tested everything. All is well now. I should have tested to see if the same problem occurred on a different hard drive. Oh well, lessons learned. Thank you Saltgrass for the help.
