Hello DevTeam members, We have a dpdk application where we are using multiple KNI's as slaves under a linux virtual interface which is acting as master. When process got SIGSEGV , we are seeing that process remains in defunct state and linux kernel is trying to release those slave interfaces in back-ground , which takes around 10 seconds each KNI , So for 30 KNi's it goes around (300 seconds, i.e 5 minutes). *Dmesg logs are as below where vbond1(Linux virtual interface) and vbond1_x are KNI's- * [Tue Dec 22 09:20:56 2020] vbond1: the permanent HWaddr of vbond1_29 - 94:40:c9:a3:b5:10 - is still in use by vbond1 - set the HWaddr of vbond1_29 to a different address to avoid conflicts [Tue Dec 22 09:21:05 2020] vbond1: Releasing backup interface vbond1_28 [Tue Dec 22 09:21:05 2020] vbond1: the permanent HWaddr of vbond1_28 - 94:40:c9:a3:b5:10 - is still in use by vbond1 - set the HWaddr of vbond1_28 to a different address to avoid conflicts Can anybody please suggest a way via which we could reduce this time. Thanks , Chetan
