read ECONNRESET after upgrading #2599
Description
After introduction of #2043, our application seems to be getting the following error (seemingly at random):
"stack": "Error: read ECONNRESET\n at TCP.onStreamRead (node:internal/stream_base_commons:217:20)\n at runInContextCb (/usr/src/app/node_modules/newrelic/lib/shim/shim.js:1168:22)\n at AsyncLocalStorage.run (node:async_hooks:335:14)\n at AsyncLocalContextManager.runInContext (/usr/src/app/node_modules/newrelic/lib/context-manager/async-local-context-manager.js:65:36)\n at Shim.applySegment (/usr/src/app/node_modules/newrelic/lib/shim/shim.js:1158:25)\n at TCP.wrapper (/usr/src/app/node_modules/newrelic/lib/shim/shim.js:1760:17)\n at TCP.callbackTrampoline (node:internal/async_hooks:130:17)\n at MysqlConnection.executeQuery (/usr/src/app/node_modules/kysely/dist/cjs/dialect/mysql/mysql-driver.js:119:69)\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n at async /usr/src/app/node_modules/kysely/dist/cjs/query-executor/query-executor-base.js:37:28\n at async DefaultConnectionProvider.provideConnection (/usr/src/app/node_modules/kysely/dist/cjs/driver/default-connection-provider.js:12:20)\n at async DefaultQueryExecutor.executeQuery (/usr/src/app/node_modules/kysely/dist/cjs/query-executor/query-executor-base.js:36:16)\n at async SelectQueryBuilderImpl.execute (/usr/src/app/node_modules/kysely/dist/cjs/query-builder/select-query-builder.js:311:24)", We use the mysql dialect for kysely which receives a pool created in this library.
the pool is created as follows:
import { createPool } from 'mysql2'; const pool = createPool({ host, // host ip string user, // user string database, // db string password, // password string port, // port timezone: 'Z', }); All versions before 3.3.5 work just fine. Right now this happens relatively often, but we can't seem to find a pattern of when/how it triggers.
Any potential help / input would be welcome.
