Memory leak in tagsrv.exe
in [LabView]
|
From: David Moerman on 15 Sep 2006 15:40 I'm seeing a memory leak in tagsrv.exe on my laptop, where I use DSC v8.2. When I close the screen (suspend the laptop), and then open it again (resume), the tagsrv.exe memory usage jumps dramatically, often to over 125MB. What is more, it appears each time I do this the memory jumps again by this amount (I'm not completely sure how consistent the incremental increase is, but I've often seen over 250MB memory usage, and as high as 500MB). Has anyone else encountered this, or does anyone have a solution? Thanks. David Moerman TruView Technology Integration Ltd.
From: Bassett Hound on 18 Sep 2006 12:40 Hi David, I have not encountered this with the DSC 8.2 module. I assume you are monitoring the Memory usage using the task Manager? Would you be able to provide a little more information about your system? How many variables are you currently using and are you running an application at the time the memory jumps? It would also be nice if you could provide before and after screen shots from when you hibernate you Laptop. Regards, Steven B.
From: David Moerman on 19 Sep 2006 13:10 Attached are some images of memory usage. Interesting, but the problem does NOT occur if I simply hibernate then resume over a short period of time. The images you see are the result of hibernating OVERNIGHT. Not sure what to make of that. I did not have LabVIEW running when the memory jump occured. The LV DSC project I'm working on has about 40 shared variables, many of which are supposed to be connected to a Modbus/TCP client via OPC. However, during this development period I do not have the hardware, so some shared variable errors result which I ignore. Also, I'm using a dataset I/O server to create batch-oriented datasets. -Dave memory1.GIF: http://forums.ni.com/attachments/ni/170/206263/1/memory1.GIF memory2.GIF: http://forums.ni.com/attachments/ni/170/206263/2/memory2.GIF
