How do I troubleshoot issues in concurrent systems?

I'm having trouble with my concurrent system. It seems to be deadlocking frequently. What should I do?

Deadlocks can be tricky! First, check for circular wait conditions. Are there any resources that multiple processes are waiting on?

Yes, I have two processes that are waiting for each other to release resources. How can I resolve this?

You can try implementing a timeout mechanism or using a resource hierarchy to prevent circular waits. Have you considered these options?

I haven't. Can you explain how a resource hierarchy works?

Sure! A resource hierarchy assigns a global order to resources. Processes must request resources in that order, preventing circular waits.
