Thread Pool Exhausted: How to Handle Without Adding Nodes

'Thread pool is exhausted' error can occur when the number of tasks exceeds the thread pool's capacity. While adding nodes can help, here are alternative solutions to handle this issue without scaling your infrastructure:

1. Increase Thread Pool Size: Adjust the thread pool's parameters to accommodate more concurrent tasks.
2. Reduce Task Volume: Re-evaluate your task scheduling strategy to decrease the workload on the thread pool.
3. Optimize Task Processing: Streamline your code or use concurrent data structures for more efficient task handling.
4. Utilize Distributed Systems: If other options fail, consider distributing tasks across multiple nodes for greater processing power.
