Hey, We have a Gluu server and a Couchbase db in our setup installed in 1 subnet in 1 data-center and in 1 region. The Gluu servers throws the following error : ``` oxtrust_persistence.log:2020-10-16 15:19:31,188 WARN [RxComputationScheduler-1] [com.couchbase.client.core.logging.Slf4JLogger] (Slf4JLogger.java:160) - [ip-172-31-11-201.us-east-2.compute.internal/172.31.11.201:11207][KeyValueEndpoint]: Got error while consuming KeepAliveResponse. oxtrust_persistence.log:2020-10-16 15:19:31,366 WARN [RxComputationScheduler-1] [com.couchbase.client.core.logging.Slf4JLogger] (Slf4JLogger.java:160) - [ip-172-31-11-201.us-east-2.compute.internal/172.31.11.201:11207][KeyValueEndpoint]: Got error while consuming KeepAliveResponse. ``` and restarting the oxauth and identity services fixes the issue but we need to know the root cause. What could cause this behavior?

I heard about `KeepAliveResponse` lately but @Mohammad.Abudayyeh, what do you think?

yeah this issue was addressed in 4.2. As i recall we found threads working in a non-singleton method. So several objects are being created and taking time causing slow downs and eventually higher heap usage leading to the slow down in operations. @Yuriy.Movchan i think we only saw this in oxauth.

Thanks, Abu. Kunal, please try 4.2 and see if you face any issue or not. Thanks!
