We have issues with basic operation after upgrading C client to version 2.7.4. Basic functionality is not working (like inserting / getting records). couchbase 2.2 community server is used (2 nodes. 1 couchbase bucket on 11222 port).
I've checked, and last working version is 2.7.2.
Please check attached logs and perl file used for testing.
In logs 10.42.14.17 is the IP of couchbase-server2.
