Problem:
After deploying the Fluent Bit Aggregator Helm Chart and running it for a few hours, it stops sending logs to Elasticsearch and Syslog, which are the intended destinations for log forwarding.
Expected Behavior:
The Fluent Bit Aggregator should consistently and reliably forward logs to the specified Elasticsearch and Syslog destinations as configured in the Helm Chart.
Steps to Reproduce:
Deploy Fluent Bit Aggregator using the provided Helm Chart.
Monitor the log forwarding functionality for a few hours.
Observe that log forwarding to Elasticsearch and Syslog ceases after a certain period.
Actual Results:
After an initial period of successful log forwarding, Fluent Bit Aggregator stops sending logs to Elasticsearch and Syslog without any apparent errors or warnings.
