Based on your description, you're experiencing a "Database Resource Limit Exceeded" error with records appearing in storage but not in the web UI. This is a known issue pattern in self-hosted Langfuse deployments.(1)

Common causes for this issue:

1. Missing events after ingestion - Events may be successfully stored in S3/blob storage but not appearing in ClickHouse or the UI. This can occur when the worker container isn't properly processing the ingestion queue.(1)

2. ClickHouse connection issues - The web container may be having intermittent connectivity problems with ClickHouse, even if ClickHouse itself isn't hitting resource limits.(1)

3. PostgreSQL table ownership issues - Migration failures can occur if table ownership isn't properly configured, preventing data from being read correctly.(1)

Troubleshooting steps:

1. Check your worker container logs specifically - the worker is responsible for processing events from storage into ClickHouse
2. Verify ClickHouse connectivity from the web container
3. Review PostgreSQL table ownership and permissions
4. Check if background migrations are stuck in "Queued" status(1)

For Azure-specific deployments, there are several documented configuration issues related to SSO and connectivity.(1)

The Troubleshooting & FAQ page(1) contains multiple discussions about similar issues including "Missing events after POST /api/public/ingestion"(1) and "Web to Clickhouse connection issue"(1) that may provide additional context.

Could you share:

• Your specific Langfuse version
• Worker container logs
• Any error messages from the web container about ClickHouse connections

This will help narrow down the exact issue.
