Greetings,
I have been hitting this issue fairly consistently for the ixgbe driver
MEMPOOL: obj=0x7ffeed1f5d00, mempool=0x7ffeecb69bc0, cookie=badbadbadadd2e55
PANIC in __mempool_check_cookies():
MEMPOOL: bad header cookie (get)
It seems to be a corruption in the mempool bound to my ixgbe port. What I
have observed is that this ONLY happens if I initialize dpdk(i.e. start
dpdk application) AFTER traffic is already flowing in through the port. If
I initialize dpdk and bind BEFORE I start traffic then things seem to work
fine.
Any clues on why this might be happening?
A bit stumped, so would really appreciate all the help I can get on this
one.
Thanks,
Kam
(bt for your reference)
