Client intermittently fails to open bucket or connect to a node during bootstrap

jberglund · July 18, 2016, 3:50pm

Environment:
Couchbase Server: Version: 4.1.0-5005 Enterprise Edition (build-5005)
Couchbase Client: couchbase-java-client-2.2.8.jar, couchbase-core-io-1.2.9.jar, rxjava-1.0.17.jar
3-node cluster (node155, node158, node159)

When I bring up my client on a 3-node cluster I will intermittently see connection issues to one node, or to the bootstrap node, on one or more of my applications on the same box bootstrapped at the same time. Sometimes everything works fine, this leads me to believe there may be a race condition.

Note that this issue is occuring frequently in our labs/testing, and the issue is easy to reproduce by putting the VM under some CPU load while the application executes the openBucket request. The issue does not appear 100% of the time under CPU load, but it does occur greater than 50% of the time. When the issue does occur, 75 seconds later a log appears showing the bucket was successfully opened (e.g. some timer popped). Some of the initial logs (right after the openBucket request) and the last few logs showing the “open bucket” response are shown below. If you need additional logs to help resolve this issue, please contact myself or jberglund.

[Couchbase] Opened bucket bwsub

The previous post listed the version of the couchbase jars we are using (shown below as well), but I verified the issue exists in older jar files (from 5 months ago) as well.
couchbase-core-io-1.2.9.jar
couchbase-java-client-2.2.8.jar
rxjava-1.0.17.jar

Thanks
