Hi @Tibin_Lukose,

This error is related to an old panic from back in the day, but the bug has already been resolved besides many other improvements:

**“error”: “could not load or initialize schema: sync schema with other nodes in the cluster: read schema: open transaction: broadcast open transaction.”**

Please be aware that you’re running a **very outdated version** of Weaviate, even before the **RAFT** mechanism was implemented for multi-node clusters.

You must upgrade to **v1.25.32** post-RAFT, despite the fact that **1.25** is still considered outdated. The latest version of Weaviate is **1.29** , so I highly recommend planning an upgrade soon - there are way too many features and great improvements that have been implemented.

Additionally, I see that you have only **2 nodes** in your cluster. I’d highly recommend reading up on the concept of **multi-node clusters**. It is generally better to have **3 nodes (an odd number)** for replication in Weaviate, rather than 2 nodes (an even number). Here’s why:

Raft-based cluster like Weaviate, a quorum is needed for the cluster to function properly. With 3 nodes, the quorum is 2, which means the cluster can continue to operate even if one node fails. In contrast, a 2-node cluster requires both nodes to be available to form a quorum, making it less fault-tolerant.

**Consensus resolution** : An odd number of nodes makes it easier to resolve conflicts and reach consensus. In a 3-node setup, a quorum can be reached with 2 nodes, providing better fault tolerance. A replication factor of 3 or 5 is commonly used as it provides a good balance between performance and fault tolerance.

I hope this helps!
