Problem to generate excel report

---

Hi there,

I have a problem to generate report from excel. Every time I run the report mango will lost its connectivity (connectivity lost and restoring connectivity) and frozen. I seems that the java perform high activity in my cpu. For your information, I am using mango v3.7.7 and java jdk-14.0.1. Hope that you can help me on this matter

best regards

The underlying Java library for generating Excel reports isn't great on memory usage, if you are generating too large of an excel file it can crash Mango. I would suggest you try running that report over a very small time range to see if that helps.
