Hi, We do not use Redis in token transactions in our application. We also reviewed the codes on github you mentioned above. We did not detect any changes in our project.
We did our experiments on the new empty Zero project. We faced the same problem in the new project.
We did our tests with jmeter with the settings you specified at https://blog.aspnetzero.com/blogs/asp.net-zero/running-load-test-on-asp.net-zero. We are getting this error even in 50 users in our environments.

Hi @tdv.yazilim
We tried with unmodified latest version and didn't get the error you are getting. Is it possible to share your JMeter test file and sample excel data file ? If we can't reproduce this error with your sample data, we can arrange a meeting and take a look at your project in an online meeting.
