How about trying to allocate more memory to Katalon Studio provided that you have enough physical memory.
See
I checked my katalon.ini now. I found I have
-Xmx2028m
Approximately 2GB. This is the default size set by the distributed zip of Katalon Studio.
My Mac has 4GB physical memory. Therefore I should specify -Xmx less than 4000m.
Faly, how much of physical memory do you have? Provided that your PC has 4GB, you may try extending -Xmx such as:
-Xmx3500m
I suppose that Katalon Studio is designed to consume larger memory for generating PDF in proportion to the number of test cases contained in the Report. Faly’s report contains more than 10 and he/she experienced problem. By extending -Xmx one would hopefully manage to finish generating PDF this time. However, when one try a PDF report which contains 100 test cases, Katalon Studio would require 10 times larger memory. Katalon Studio seems not to be tolerant enough for large set of test cases in a report with a limited size of memory. So, you should be reminded that there is a upper limit of Report size accordingly to the physical memory size of your PC.
In short, you should mind either of
- do not make your report too large
- get PC with larger physical memory to host larger -Xmx for Katalon Studio to let it generate a large PDF
