java.lang.OutOfMemoryError: Java heap space
Posted: Wed Apr 16, 2025 2:42 pm
Hi!
I use:
*.ditamap transformation scenario - "DITA Map PDF - based on XSL-FO" and my customization.dir and custom DITA-OT.
I added topics to the *.ditamap step by step (over 400 pdf pages) and caught an error: java.lang.OutOfMemoryError: Java heap space.
So I edited parameter -Xmx<value> in my "oxygen23.1.vmoptions" file to the value 16000m (the "Copyright" tab in "About" window displayed the set value of the amount of memory), but it didn't help. Increasing the value of parameter "maxJavaMemory" in my scenario did not help either.
Here is the end of my console output log:
Need help, advice 
.
Thanks in advance.
