Open mombe090 opened 3 years ago

mombe090 commented 3 years ago

Hi @ankitvaishnav as disccuss, when we try to do the load test on the platform with more request 4000 in this case, we faced 504 bad gateway issue. After investigation with @chandra, we saw the issue inside the keycloak pod with the logs below
