Are there considerations about resource recycling by the process, not by the OS?

Are there considerations about resource recycling by the process, not by the OS?

[Zhangkun (K)]

Hi,
   I develop the program with the use of dpdk and the process is core dump when the program is started.
The process is crash in case of initing memory failed and calling rte_panic function.
 I search all rte_panic function in the dpdk, and find it so many. Therefore, in case the pr ocess happen fail,
it will abort. The resource allocated before is not released by the process, but by the OS system.
So I have a question: Are there considerations about resource recycling by the process, not by the OS ?

Hi,

you may try
 $ gdb your_program
 gdb> b rte_panic
 gdb> run
 stopped at rte_panic
 gdb> bt

sorry, it is not answer for your question.
by the way, do you run the program as root?

Hi,
    Yes, the program is running as root.
    I want to know if or not the DPDK Community considers about resource recycling.

Can you perhaps send on the log and the traceback from the panic call. From the error message we may be able to tell you why your process is failing.

Hi Zhangkun,

Do you talk about resource management of DPDK when a process is finished?
If so, I guess DPDK doesn't care so much about freeing resources once
allocated by the process.
For example, there is no function to free a mempool.

Thanks,
Tetsuya
