While preparing migration of our SW from Couchbase server 1.81 to a newer version, I’ve encountered a strange error: “Failed to store the key on the server: Network failure”
After lots of debuging of our code, I’ve finally found that the problem is this key: “47-2014-04-18-balance” (without quotes).
Using plain https://github.com/couchbase/libcouchbase/blob/master/example/syncmode/main.c with just the key changed from “mykey” to “47-2014-04-18-balance” triggers the error.
- client 1.0.x and server 1.8.x works
- client 2.3.x and server 2.x works
What is so special about this key?
