【rte_malloc & free】the issue of crashing at malloc_elem_free

[halsey.pian at longsys.com]

Dear All,

I am suffering an crash issue recently. My app based on SPDK/DPDK uses rte_malloc_socket and rte_free to use hugepage feature in multi-threads and async programming environment.

Unfortunately, It would crashed sometimes, and I found that it usually crashed caused by the element's size = 0 in function malloc_elem_free at line 570 in file malloc_elem.c during calling rte_free, the call stack is as the attachment.

I am not sure if I miss some information related async and multi-thread programing using DPDK rte_malloc module. 

BTW, it works fine when I switch to kernel's malloc/free.

OS: Fedora 32
DPDK Version: 21.05.0

Could you please provide some information or advices? Thanks a lot.



Best Regards
Halsey Pian
