RE: Killing caRepeater on Windows 10

[Mark Rivers via Tech-talk <tech-talk@aps.anl.gov>]

Ø  When I use caget, it appears both under Details *and* under Users on my Windows 10 system.

 

What version of caget are you using?

 

I just tested on my system with caget from base 7.0.3.1 and I don't see that.

 

Here I kill caRepeater, run caget, and then see that caRepeater is indeed running:

 

****************************

J:\epics\devel\dxp>taskkill /f /im caRepeater.exe

SUCCESS: The process "caRepeater.exe" with PID 9896 has been terminated.

 

J:\epics\devel\dxp>h:\epics\base-7.0.3.1\bin\windows-x64-static\caget 13IDA:m1

13IDA:m1                       -0.250184

 

J:\epics\devel\dxp>tasklist /fi "imagename eq caRepeater.exe"

 

Image Name                     PID Session Name        Session#    Mem Usage

========================= ======== ================ =========== ============

caRepeater.exe                8576 Console                    1      3,640 K

****************************

 

When caRepeater is running this is what I see in Task Manager/Users and /Details.

 

 

 

 

I don’t see caRepeater in either screen.

 

It seems that either caget has changed behavior, or something is configured differently on your Windows 10 system from ours?

No, unfortunately that is where I expected to find it, but it does not appear there if caRepeater was started by another EPICS application.  It did appear in the Processes tab in Windows 7, but does not appear in the Details tab in Windows 10.

Hi Mark,

 

I believe that the other option to find this process in the Windows 10 Task Manager is under the 'Details' tab (which to me looks like the Windows 7 'Processes' tab) .

 

Best regards,

even though it is running and the executable file cannot be deleted.

Note that in this case it is nested under PointGreyApp.exe, which is my IOC.

Task Manager may only be showing nested processes 2 deep, rather than 3 deep?
