We have an openemr based on a single docker , however While perfroming the perfromance testing using testing tools like Jmeter we are faced “site id is missing from session data” .
However in multiple browser sessions we are not facing the same issue, only while using Jmeter with concurrent request we are facing the issue.
We learned that this similar issue occurs in multi instance platforms [ eg: kubernetes pods replicas] but there we got fixed via redis caching [verified in multiple browser sessions ]
However while we perform testing using Jmeter only we are facing same issues in both single and multi instances
Any suggestions pls ?
