Hi experts, Has anyone seen this below crash back-trace happening during the TX? Cras was seen in this function rte_ipv6_phdr_cksum
The QA was trying to run a call model with about 200 UEs trying to connect to VPP and the crash was seen. This doesn't always happen. Any pointers on this is highly appreciated.
