Description
Build: 6.5.0-3688
Scenario:
- 4 node cluster, couchbase bucket (replicas=2)
- Loaded 1K docs with durability=MAJORITY
- Killed 'beam.smp' on one of the node (172.23.105.205)
- Perform CRUD operation on active vbuckets not involving the killed nodes' active vBucket with same durability levels as before
Observation:
Memcached crashes after step #3 with prints,
*** Error in `/opt/couchbase/bin/memcached': free(): invalid pointer: 0x00007ffa3d554000 ***{{ }}
After restarting the server also, observing Memcached crashing continuously.
Expected behavior:
- Memcached should not crash when other process go down unexpectedly
- After restarting the couchbase-server service, Memcached should not crash multiple-times
Service 'memcached' exited with status 134. Restarting. Messages:
