wohali opened a new issue #1358: error: function_clause, chttpd_db:update_doc_result_to_json/1 URL: https://github.com/apache/couchdb/issues/1358 Under heavy load and insufficient CPU, a 3-node cluster produced a large number of function_clause errors. This is one of these errors. This one followed after a large number of `fabric_worker_timeout` errors on a heavily contended shard on all 3 nodes, as shown below: ``` [error] 2018-05-28T07:49:11.151000Z couchdb@node1 <0.733.9> ccdf060570 fabric_worker_timeout update_docs,'couchdb@node1',<<"shards/40000000-5fffffff/db.1519652499">> [error] 2018-05-28T07:49:11.151000Z couchdb@node1 <0.733.9> ccdf060570 fabric_worker_timeout update_docs,'couchdb@node3',<<"shards/40000000-5fffffff/db.1519652499">> [error] 2018-05-28T07:49:11.151000Z couchdb@node1 <0.733.9> ccdf060570 fabric_worker_timeout update_docs,'couchdb@node2',<<"shards/40000000-5fffffff/db.1519652499">> [error] 2018-05-28T07:49:11.151000Z couchdb@node1 <0.733.9> ccdf060570 req_err(715961248) unknown_error : function_clause [<<"chttpd_db:update_doc_result_to_json/1 L931">>,<<"lists:map/2 L1238">>,<<"chttpd_db:db_req/2 L448">>,<<"chttpd:process_request/1 L295">>,<<"chttpd:handle_request_int/1 L231">>,<<"mochiweb_http:headers/6 L91">>,<<"proc_lib:init_p_do_apply/3 L240">>] [error] 2018-05-28T07:49:12.607000Z couchdb@node1 <0.21277.17> -------- fabric_worker_timeout update_docs,'couchdb@node1',<<"shards/40000000-5fffffff/db.1519652499">> [error] 2018-05-28T07:49:12.607000Z couchdb@node1 <0.21277.17> -------- fabric_worker_timeout update_docs,'couchdb@node3',<<"shards/40000000-5fffffff/db.1519652499">> [error] 2018-05-28T07:49:12.607000Z couchdb@node1 <0.21277.17> -------- fabric_worker_timeout update_docs,'couchdb@node2',<<"shards/40000000-5fffffff/db.1519652499">> ```
