Have you faced deadlocks during parallel batch processing?

Yes, in parallel processing of embedded system or IoT device batches, deadlocks can occur due to competition for resources, such as simultaneous access to shared data or peripherals.

To prevent deadlocks, the following are used:

• Clear lock ordering
• Use of timeouts when acquiring resources
• Minimizing lock holding time
• Avoiding nested locks

In practice, it is important to analyze logs and use tracing tools to identify and eliminate deadlocks.
