Mark,

These numbers were for our production IOCs which are being run on a cluster and using procServ.

I looked at an IOC run without any of this and it showed no growth in memory consumption. So I am working on investigating the differences between these set-up.

Thanks for your help.

John

Mark,

An IOC which is not acquiring from the camera grows at ~ 0.15 MB per minute. (resident memory grows, virtual memory is constant)

An IOC acquiring an image (1116x836, 5.5 Hz), no plugins, grows at ~ 0.24 MB per minute

[ note: 0.24 MB/min --> 10 GB after a month]

Enabling NDPluginStdArrays, NDPluginOverLay, NDPluginROI, NDPluginStats doesn't seem to produce additional memory growth.

Sorry, I should have said, Linux. I will investigate and report.

Hi John,

Is this on Linux or Windows?

Can you use “top” or other memory monitoring tools to see if memory usage increase corresponds to specific actions, such as stopping and starting the camera, errors about dropped frames, use of specific plugins, etc.?

All,

We are using ADVimba with Mako G319B cameras. Over a period of three months memory usage has grown by an order of magnitude. Has anyone else encountered this?

Firmware Version 00.01.54.21000

SDK Version 1.8.0

Driver Version 1.1

ADCore Version 3.7

[ I can try newer version of ADVimba in january.]
