2019-09-09 12:56:29 UTC - Ravi Shah: I am Running a Load test on standalone Pulsar setup and notice some strange behavior. I am running 5M request.

1. 5M req with 100 concurrency - It fails with Producer queue full error
2. 5M req with 1 concurrency - Its runs successfully
For both the cases i use maxPendingMessages=100000000
Anyone any idea why this strange behavior?

    at org.apache.pulsar.client.admin.internal.BaseResource.getApiException(BaseResource.java:162)` when I try to get the subscriptions from a topic, what could cause this error?
This is a partitioned topic and the topic exists in the brokers
