Weaviate gRPC Deadline Exceeded Error

How to fix it

Try these in order — the most common fix is first.

1. 1. Check server health

   Copy steps
   1. Look for OOM events, CPU saturation and network issues
   2. On Weaviate Cloud, open a support ticket since forum staff cannot see cluster metrics
   Did this fix it? Yes No

2. 2. Tune timeouts and batching

   Copy steps
   1. Raise MODULES_CLIENT_TIMEOUT if the vectorizer is slow
   2. Use a fixed batch size instead of dynamic batching
   3. Set ASYNC_INDEXING=true to decouple indexing from writes
   4. Enable trace log level to watch ingestion
   Did this fix it? Yes No

3. 3. Last resort

   1. Generate embeddings with your own client and insert vectors directly (workaround used in a forum thread)
   Did this fix it? Yes No

Symptoms

Messages like 'Query call with protocol GRPC search failed with message Deadline Exceeded' or 'GRPC batch failed ... Failed to send all objects in a batch'.

Why it happens

• Server short on CPU or memory (the forum's usual answer)
• Vectorizer module call exceeding MODULES_CLIENT_TIMEOUT (default 50s)
• Dynamic batch sizing overwhelming a fast local vectorizer
• Network latency or packet loss
