Out of memory issue

[vuquochuy]

Hello,

I’m facing the issue “Out of memory: job could not be finished because too much memory was used.” while downloading an Excel file retrieving some general information from the entities. I’m actually in the dev version of my app with about 30 entities within the workspace. For the prod version, all the workspaces contain less entities and the download works well. Have you any ideas about the origins of the memory issue here? What is the memory limit that raises this error?
Thanks.

Best regards,
Huy

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.
