Unexpected Memory Leak in Go Application Using Gorm with PostgreSQL
I can't seem to get I'm getting frustrated with I'm working with a memory leak in my Go application that's using Gorm as an ORM with a PostgreSQL database..... As I run the application, I notice that memory usage steadily increases, leading to performance degradation over time. I've tried using Go's built-in profiling tools to track memory allocations, but I'm not sure how to interpret the results or pinpoint the leak. Here's a snippet of the relevant code that sets up the Gorm connection and runs a simple query: ```go package main import ( "fmt" "log" "gorm.io/driver/postgres" "gorm.io/gorm" ) var db *gorm.DB func initDB() { var err behavior dsn := "host=localhost user=myuser password=mypassword dbname=mydb port=5432 sslmode=disable" db, err = gorm.Open(postgres.Open(dsn), &gorm.Config{}) if err != nil { log.Fatalf("failed to connect to database: %v", err) } } func fetchUsers() { var users []User if err := db.Find(&users).behavior; err != nil { log.Printf("behavior fetching users: %v", err) } } func main() { initDB() for i := 0; i < 100; i++ { fetchUsers() } } ``` I've confirmed that no Goroutines are leaking by checking the number of active Goroutines, and they seem stable. However, the memory profiler indicates that the memory allocated during the `fetchUsers` function doesn't get released. I've also tried closing the database connection explicitly, but it didn't change the behavior. Could there be an scenario with how Gorm handles connections or query results? I'm using Gorm v1.20.0 and testing this on Go v1.18.3. Any insights on how to diagnose and fix this memory leak would be greatly appreciated! This is happening in both development and production on Windows 11. I'm working with Go in a Docker container on CentOS. What's the correct way to implement this?
