Investigate why Lighthouse/Lighthouse combo experiences issues with missing duties

[boulder225]

🎯 Problem to be solved

Lighthouse/Lighthouse combo (running with distributed flag), although gets slightly better over time , is experiencing issues with missing duties, specifically:

• aggregate_attestation duties are being missed.
• sync_committee_contribution duties are being missed.

This could be due to another misconfiguration probably in kurtosis. Also, the beacon node score is low (97%), and VC loads keys extremely slow (15 minutes or longer).

🛠️ Proposed solution

• [ ] Investigate the root cause of the missing aggregate_attestation duties and address any underlying issues.
• [ ] Investigate the root cause of the missing sync_committee_contribution duties and address any underlying issues.
• [ ] Review the validator client's logs and configuration to identify potential factors contributing to the missed duties.
• [ ] Investigate the cause of the low beacon node score and address any underlying issues.
• [ ] Leverage the https://lighthouse-book.sigmaprime.io/validator-manager-create.html#1-create-the-validators guide to generate a validators.json file, which may help improve the key loading performance.
• [ ] Explore alternative methods or optimizations for loading keys more efficiently, instead of the current one-by-one approach in the run.sh script.
