Situation:
- Using Mongoose v4.7.6
- Working with MongoDB v3.2.11
Currently facing issues regarding database errors in my software.
Encountering a problem where mongoose requests hang when the database is disconnected and only resume once reconnected.
This is what occurred:
- Software launched successfully
- Established connection to the database using Mongoose
- Interrupted the mongod process using Ctrl+C
- Received both the "Disconnect" and "Close" events from mongoose
- Initiated a find(...) request
- Find request stuck indefinitely
Attempted Solutions:
Experimented with implementing the bufferCommands option in my schema, which according to the documentation, should trigger an error if no connection is available. However, the issue persists.
Snippet of My Code:
mongoose.createConnection(..., {
server: {
// Reconnect feature disabled from mongoose
auto_reconnect: false,
socketOptions: {
// Enabling keepAlive is advisable for long running applications
// Without it, "connection closed" errors may occur unexpectedly after some time.
// As per mongoose documentation
keepAlive: 1,
},
},
})
