Hi,
I am seeing repeatedly issues when configuring VPP with worker threads.
My platform is a multi-socket one (NUMA) so I want to PIN the VPP threads where
my NIC card naturally belongs too (Node 3, first core is #48).
The problem I see is:
Anytime I enable the worker-threads VPP core-dumps while the traffic flows
through it (I'm running iperf3). On the other hand, it works just fine when
executed in single-thread (just the main thread).
In order to clear the air, I decided to also try without the NIC (thinking of
some issues with the PMD) and took the intra-vm scenario. Also in this case, VPP
core-dumps when executing in multi-threads mode.
Below, you can find the configuration I am using. Any ideas would be much
appreciated.

unix {
interactive
nodaemon
log /tmp/vpp.log
full-coredump
}
api-trace {
on
}
api-segment {
gid vpp
}
cpu {
main-core 0
skip-cores 47
workers 2
}
Regards,
Marco
