Enterprise Edition 6.5.0 build 3821
core-io-2.0.0-alpha.5.jar
java-client-3.0.0-alpha.5.jar
Description
Server build: 6.5.0-3821
Client build:
core-io-2.0.0-alpha.5.jar
java-client-3.0.0-alpha.5.jar
Scenario:
- 4 node cluster, Couchbase bucket (replicas=2)
- Start loading documents targeting the active vbuckets persent on node-1 (10.112.191.101)
- Kill Memcached when doc_loading is running in background
Observation:
Memcached on node-1 recovers successfully. But new doc_create requests are not dispatched from clients's end (Verified using doc_req.pcapng).
Seeing 'com.couchbase.client.core.error.RequestTimeoutException' for un-dispatched requests from client end.
Expected behavior:
Doc create request should be resumed once the memcached restarted successfully in cb-server.
