Hello everyone,

We are using memory allocation for packets in our DPDK-based application. However, we are observing a de-sync issue where, during debugging, we see logs indicating that a packet is allocated twice without being freed in between.

To diagnose the issue, we added logging at both the time of allocation and deallocation. From the logs, we noticed:

• The same memory address is allocated/shared twice without a corresponding free operation.
• This is causing inconsistencies in packet handling.

Our Questions:

1. Is this a known issue in DPDK 18.08?
2. Is there any existing patch or workaround available for this problem?
3. What could cause a scenario where a packet is allocated twice without freeing?
4. What debugging approaches or tools would you recommend for tracking such memory allocation inconsistencies?

Additional Details:

• DPDK version: DPDK 18.08.0 version 16

Would appreciate any insights or debugging tips from the community!

Thanks,
Adesh
