Out of memory issue

[mslootweg]

Hi @vuquochuy ,

A memory issue could be because of a number of reasons. If an Excel file is created because of information from entities, I would assume that more entities => more data => more memory usage. A general first approach would be to check whether the code was written such that it wastes memory unnecessarily. This could be done by profiling memory, like mentioned in this post:

Memory error

You can profile the memory using the the package using this memory profiler package in your development environment. install the package in your venv using: pip install memory_profiler Start VIKTOR with the profiler with: mprof run viktor-cli.exe start use the app as normal in the browser. Afterwards you can check the memory usage using: mprof plot If the plot gives an error, try to install PyQt5 in your venv. pip install PyQt5

Every app has a set computational resources, which include disk space and memory (RAM). This is generally set to the default values provided. These can be adjusted through a request sent to us.
