I am developing the customer bill validation process. The bill is a readable PDF. I am doing PDF extractor to get the data and validate the entries. I have to process thousands of files continuously. after processing few hundreds of files I am getting an out of memory issue as given below.
“Job Stopped with an unexpected exit code : 0xE0434352”
I am using .NET framework version 5.0, UiPath Studio Version 2022.4. Ram is 16GB and Processor 4 Core.
I extract the each bill and store in the data tables and do the required validation for that and then move to next bill.
And also I am not using excel files in the process. But I am writing validation errors to the csv files.
Appreciate if you can help me to sort this error. I am doing multiple validations using different workflows.
Complete stack trace is given below:
