2.0 DP3
originally reported on Debian GNU/Linux 6.0
reproduced with slight differences on Ubuntu 11.10 64 bit
Description
Running initially with a PHP client, but then simplifying the test and running both clustered and unclustered basic workload tests shows that on both micro instances and large instances basic workload tests timeout and/or fail. On micro instances, this is shows up particularly quickly even in a single node localhost situation.
Steps:
- Set up EC2 instance
- Install Couchbase Server 2.0 DP3
- Run /opt/couchbase/bin/memcachetest -l -t 32 -h localhost:11211
Observed behavior:
Many errors such as:
ASCII set failure: SERVER_ERROR proxy downstream timeout
ASCII set failure: SERVER_ERROR proxy downstream timeout 10.48.43.67
ASCII set failure: SERVER_ERROR proxy out of downstreams
ASCII set failure: SERVER_ERROR proxy downstream timeout
<3944> isn't there anymore
...
Also note that the observed throughput would start high, slow down, speed up, etc.
Expected behavior:
Workload should degrade or possibly timeout in an extreme workload case, but not be issuing out of downstreams. The server should definitely handle this workload without errors.
