Java Heap Space - OutOfMemoryError

MikeAMCO · May 6, 2020, 8:22pm

I am working on an application that requires the reading of images from client files and displaying images in the interface. Later these images can be inserted into a MySQL database. I have working scripts for all required functions - reading bytes from file, visualizing in either a label or image component (I tried both methods to see if there would be any differnce in the memory issue), and then inserting into a database. In this case, I would like to focus solely on the image component and its code.

The problem that I am experiencing is when I load the bytes into the image or label component the memory gets incrementally higher until I reach the 1024MB limit. Smaller images such as 720 X 1280 will cause used memory increase up to 4MB increases while 3000X4000 images will cause used memory increases up to 40MB. These values never decrease; so ultimately, I will get this error. The following graph demonstrates how the memory is consumed every time I select a new file.

I use the file explorer component to select a file, then I read the data and write to a temp file which is than written to the path property of the image component. Here is the interface:

The error that is thrown is:

I have included all of the event code below, but this is the line that will ultimately cause the error:
img = ImageLoader.getInstance().loadImage(filename). Please note that I have isolated the memory usage increase to this part of the code.

if event.propertyName == 'path':
	
	from com.inductiveautomation.ignition.client.images import ImageLoader	

	imgComponent = event.source
	imgComponent.rotation = 0
	imgComponent.imgRotationValue = 0

	# Get image component size from Custom Properties
	initImgCompWidth = imgComponent.initImgCompWidth
	initImgCompHeight = imgComponent.initImgCompHeight
	
	#resize image component to initial values in custom properties
	system.gui.transform(component=imgComponent, newWidth=initImgCompWidth, newHeight=initImgCompHeight)

	#Find Aspect Ratio of Original Image
	filename = imgComponent.getPath()
	img = ImageLoader.getInstance().loadImage(filename) #this line causes the JVM heap error in the client or designer 
	imgW = img.getWidth()
	imgH = img.getHeight()
	imgRatio = float(imgW) / float(imgH)
	
	if imgRatio > 1: # means that picture has more pixels in the x (width) than y (height)
		modImgCompWidth = initImgCompWidth
		modImgCompHeight = int(initImgCompHeight / imgRatio)

	else:
		modImgCompWidth = int(initImgCompWidth * imgRatio)
		modImgCompHeight = initImgCompHeight
	
	event.source.modImgCompWidth = modImgCompWidth
	event.source.modImgCompHeight = modImgCompHeight
	
	#resize the image component to maintain image perspective
	system.gui.transform(component=imgComponent, newWidth=modImgCompWidth, newHeight=modImgCompHeight)
	
	# Set Strech Mode to "Parameters"
	imgComponent.setStretchMode(2)
		
	#Set Component Image Bounds
	imgComponent.setStretchHeight(modImgCompHeight)  
	imgComponent.setStretchWidth(modImgCompWidth)

Additional information showing the designer “About” page, designer performance, gateway performace (not an issue), and project properties:

Finally, my development machine has 64bit architecture with more than 32GB of RAM.

What, if any solutions are available for this issue?

Thank you in advance.

Kevin.Herron · May 6, 2020, 8:27pm

Does it still happen if you modify your code to call ImageLoader.getInstance().loadImageNoCache() instead?

MikeAMCO · May 6, 2020, 8:40pm

Hello Kevin,

Just tried loadImageNoCache() and memory usage still increasing.

For the second argument, I used a null to bring the file in at its natural size, bu I got an error. Maybe configuring the dimension argument could help.

Kevin.Herron · May 6, 2020, 8:44pm

Hmm, using None for the null parameter should work.

Does it increase and crash still, or just increase and eventually GC?

MikeAMCO · May 6, 2020, 8:50pm

Increases to a crash. Here is the graph:

Here is the code:

	from com.inductiveautomation.ignition.client.images import ImageLoader	

	imgComponent = event.source
	imgComponent.rotation = 0
	imgComponent.imgRotationValue = 0

	# Get image component size from Custom Properties
	initImgCompWidth = imgComponent.initImgCompWidth
	initImgCompHeight = imgComponent.initImgCompHeight
	
	#resize image component to initial values in custom properties
	system.gui.transform(component=imgComponent, newWidth=initImgCompWidth, newHeight=initImgCompHeight)

	#Find Aspect Ratio of Original Image
	filename = imgComponent.getPath()
	img = ImageLoader.getInstance().loadImageNoCache(filename, None) #this line causes the JVM heap error in the client or designer 
	imgW = img.getWidth()
	imgH = img.getHeight()
	imgRatio = float(imgW) / float(imgH)
	
	if imgRatio > 1: # means that picture has more pixels in the x (width) than y (height)
		modImgCompWidth = initImgCompWidth
		modImgCompHeight = int(initImgCompHeight / imgRatio)

	else:
		modImgCompWidth = int(initImgCompWidth * imgRatio)
		modImgCompHeight = initImgCompHeight
	
	event.source.modImgCompWidth = modImgCompWidth

One of our defect analysts is going to try to reproduce this and see if it’s a memory leak in Vision.

MikeAMCO · May 6, 2020, 11:49pm

Sounds good. Thank you!

MikeAMCO · May 12, 2020, 9:19pm

Any news?

Kurt.Larson · May 12, 2020, 11:05pm

Can you disable caching on the image component? The images aren’t being stored in the cache due to the script anymore, but instead are being retained from the image component. Make sure to still keep the loadImageNoCache method within your script.

We’ll look into implementing some pruning mechanism to cleanup the cache, but for now, you can either bypass cache altogether or periodically call resetCache().

MikeAMCO · May 14, 2020, 2:59pm

Thank you Kurt.

The solution worked.

In the image component´s Property Editor, I set Use Cache to False while using loadImageNoCache(filename, None). The memory issue was resolved.
