We are testing a new system architecture and couch keeps crash under relatively light loads, about 40 concurrent requests. Any thoughts? What I've tried: - Tweaking settings http://wiki.apache.org/couchdb/Performan - Testing with both Siege and AB - Tried different cloud-based servers. Doesn't seem to be a memory issue, as there is always plenty of available memory. thanks joe --047d7bea3a64a2eea004eb4b4110--
