This page shows the troubleshooting for operating a Vald cluster.

Insert Operation

Vald Agent NGT crashed at the insert process.

Let’s check your container limit of memory at first. Vald Agent requires memory for keeping indexing on memory.

Search Operation

Vald returns no search result.

There are two possible reasons.

  1. Indexing has not finished in Vald Agent
    • Vald will search the nearest vectors of query from the indexing in Vald Agent. If the indexing process is running, Vald Agent returns no search result.
  2. Too short timeout for searching
    • When the search timeout configuration is too short, Vald LB Gateway stops the searching process before getting search result from Vald Agent.

Vald Agent NGT requires an AVX2 processor for running. Please check your CPU information.
