Hi John. Thanks for your response. I built my own VPP on Debian 8 and my gcc version "gcc (Debian 4.9.2-10) 4.9.2". Since I had problem in building vpp with my gcc, I made changes on code which are available in the following link. https://paste.ubuntu.com/p/kn34fxwSjb/
I don't know exactly what debug image is. But I changed -O2 parameters in vpp.mk file into -O0. After doing this, I ran the test again and there was no SIGSEGV. I took my test again with a vpp which was built by -O2 parameter and again I saw SIGSEGV signal. The following link shows the back-trace of new test. https://paste.ubuntu.com/p/x98qjjxtBS/ Here is my startup.conf. https://paste.ubuntu.com/p/G5pHbW4PGY/ Do you want me to send my vpp deb files?

I was able to configure trex the way you had, but was able to run the test without a crash overnight. Could you send us your vpp startup.conf? Also, is this your own private build or downloaded from package cloud? Would you be able to build and run a debug image?

I did apply the patch you'd sent on vpp 19.01. Again I got SIGSEGV by running the same test, but it occurred in a different part of the code. Here is the back-trace of gdb: https://paste.ubuntu.com/p/fpmynt3BCm/ best regards ________________________________ From: Ole Troan <otr...@employees.org> Sent: Monday, March 11, 2019 2:36 PM To: Rubina Bianchi Cc: vpp-dev@lists.fd.io Subject: Re: [vpp-dev] getting segfault in execution of vpp 19.01 having nat configuration with trex Hi Rubina, This looks like a fault in a local UDP application (BFD) registering to receive UDP packets, even when not configured. That should be fixed in: https://gerrit.fd.io/r/#/c/18188/ Great if you can verify when that is merged. Cheers, Ole > I configured nat on vpp 19.01 and wanted to test it using trex.
