Error in SNAP

[Karolina]

Hi everyone,
I have recently been working in the SNAP program.
I generate interferograms from two satellite images (SLC) Sentinel 1.
But often during processing in the program appear errors that prevent me from further work.
The most common errors are:
Java heap spatial.
GP overhead limit exceeded.
Content is not allowed in prolog.

I have no idea what they result from and how I can eliminate them.
Can any of you help me?
I will be grateful for any help.

Regards
Karolina

please have a look at this answer: Java heap Error

How do we solve the “Content is not allowed in prolog” issue?

Regarding the prolog error.
Is this thread helping?

Snap Error Opening Manifest.safe error

I got into the same problem on my MAC (High Sierra) and deleting the .DS_Store did not help. But I noticed that if I rename the manifest.safe file to manifest.xml everything works well. So the quick fix I am using is copying the file programmatically from manifest.safe to manifest.xml before trying to open it and this works well: shutil.copyfile(pathdir + “manifest.safe”, pathdir + “manifest.xml”) product = snappy.ProductIO.readProduct(pathdir + “manifest.xml”)

Hi, yes it did help for this error, thank you.
Then I got to the next one, requiring modifications to the init.py (Using mask file with KMeansClusterAnalysis in python).
Trying to solve that currenly.

I thought that was already fixed. But I did now (SNAP-1056). Will be included in the next release.
