Hi All,

I'm working on the SAP web Application and I'm facing error while executing the scenario through controller error description mentioned below.

Error Details:

Error: 27638 Server https://URL has sent HTTP2 GOAWAY frame with status code "PROTOCOL ERROR"

It is working fine in the Vugen but fails while executing the scenario through controller.

I have iterated the script with 40 Vusers and 40 test data(which is not data dependent). the script contains 8 transactions which is having only display transaction. the same which I tried to execute via controller some of the transaction is failing because of the HTTP2 GOAWAY error(transaction failure rate is 10%).


Tried with fixed think time of 15 sec and 30 sec respectively with 20 users and it worked fine(only few 3-4 transaction failed) in the controller but when I tried with same 20 Users with random think time of recorded think time(30Sec) 50% to 150% the transaction failure rate is more.

Note: We have to execute with random think time.


Any solution for this issue and Thanks in advance.
