How can I troubleshoot concurrency issues in my Ruby application?

To troubleshoot concurrency issues in Ruby, start by identifying the specific problem. Are you facing deadlocks, race conditions, or performance bottlenecks?

I'm dealing with race conditions, especially when multiple threads access shared resources.

In that case, consider using mutexes to synchronize access to shared resources. You can also explore using thread-safe data structures.

What are some common pitfalls when using mutexes?

Common pitfalls include forgetting to lock the mutex, leading to race conditions, or causing deadlocks by locking multiple mutexes in the wrong order.

How can I test for race conditions in my code?

You can use tools like RSpec with the rspec-retry gem to run tests multiple times, or use the concurrent-ruby gem to simulate concurrent access.
