concurrency issue / race condition (will sometimes fail under stress)

["Cholleti, Harika" <Ha...@gridpoint.com>]

I was doing  concurrent 50-Calls to POST data for 50- different users .For each post-call iam sending different data every 15 mins or 5 mins. Irrespective of running for  30-mins. In 50-calls one calls  get fails because of  that data doesnot exist for the user. When I checked my payload I was passing  correct data to the user( verified sending payload on other client worked successfully). As, I was running my test for 1 hour. 30mins one of the request failed.At 35 min it will be successful again. Not sure exactly it is because of race condition or  cache issue of client.

In JSR223 Sampler I was generating payload. Multi-Intervaldata HTTP Request1 ( post call) I was posting data.
