[dpdk-users] assert failure while allocating cmbuf

[dpdk-users] assert failure while allocating cmbuf

[Alex Kiselev]

Hi.

I've got an error in my application and I need an advice how to find
what could cause it.
The error was RTE_ASSERT(rte_mbuf_refcnt_read(m) == 0) failure in
rte_mbuf_raw_alloc()
while my app was trying to allocate a new mbuf from a control memory
buffer pool using
rte_ctrlmbuf_alloc(). So, that kinda mbufs are used only for passing
messages via rings in my app.

What should I look for in order to find a bug in my app?

Thank you.

P.S.
So far I've got only one occurrence of the bug and I am trying to
reproduce it running
the same stress test.

Alex,
Are you aware of the ongoing deprecation process of ctrl_mbuf API ?
See for example, this thread:
http://dev.dpdk.narkive.com/EifFAcs5/dpdk-dev-rte-ctrlmbuf-init-and-ctrl-mbuf-flag-are-not-used-shouldn-t-they-be-removed-and-deprecated

Regards,
Rami Rosen
