Hi Community,

I’m currently facing a critical issue with **Odoo 16 Enterprise Edition**, which we use as a **warehouse management solution** for stock and order synchronization across multiple third-party marketplaces.

For the past **three months**, Odoo has been consuming excessive memory, eventually leading to **Out of Memory (OOM) crashes** on our VM. Initially, this occurred once every **two to three weeks**, but now it happens **3–5 times per day**, severely disrupting operations.

### **Issue Details**

- **Symptoms:** Odoo's memory usage keeps increasing until the VM crashes due to OOM. Even after rebooting, the memory gradually climbs again until it crashes.

- **Current Workaround:** We set up an **Uptime Check on GCP**, which detects when the Odoo web service becomes unreachable and automatically restarts the VM.

- **Users:** Internal use only, with **60–75 concurrent users** at max.

- **Initial Suspicions:** I suspected that the **scheduled queue jobs** syncing to marketplaces every **10 minutes** were causing the issue. However, even when there’s low order activity, Odoo still crashes.

- **Scaling Attempt:** Upgraded the instance from **38GB RAM** to **50GB RAM**, but the issue persists with the same pattern.

### **Environment Details**

#### **Compute Engine (GCP)**

- **Original Spec:** N2 – **24 vCPUs, 38GB RAM**

- **Current Spec:** N2 – **24 vCPUs, 50GB RAM**

#### **CloudSQL (PostgreSQL for Odoo Database)**

- **PostgreSQL 14** – **40 vCPUs, 75GB RAM**

#### **Odoo Configuration (50GB RAM)**

```SCHEME

; === 18 Workers Config for 50GB RAM ===

workers = 18 

max_cron_threads = 4 

limit_memory_soft = 38654705664  ; 36GB (2048 MB × 18)

limit_memory_hard = 48318382080  ; 45GB (2560 MB × 18)

limit_request = 4096 

limit_time_cpu = 3000 

limit_time_real = 6000 

```

### Questions

1. **What could be causing Odoo to keep consuming memory until it crashes?**

2. **How can I effectively debug and monitor which process or worker is using excessive memory?**

3. **Has anyone experienced similar OOM issues with Odoo, and what solutions worked for you?**

Any insights or recommendations would be greatly appreciated. Thanks!
