Hi all,
I sent 40000 MACs l2 packets to VPP, then it crashed, and below is the stack.
out of memory? How can I get this correct?

## In the VPP there is one main thread and optionally the user can create
worker(s)
## The main thread and worker thread(s) can be pinned to CPU core(s) manually
or automatically
## Manual pinning of thread(s) to CPU core(s)
## Set logical CPU core where main thread runs
#main-core 1
## Set logical CPU core(s) where worker threads are running
#corelist-workers 2-3
## Automatic pinning of thread(s) to CPU core(s)
## Sets number of CPU core(s) to be skipped (1 ... N-1)
## Skipped CPU core(s) are not used for pinning main thread and working
thread(s).
## The main thread is automatically pinned to the first available CPU core and
worker(s)
## are pinned to next free CPU core(s) after core assigned to main thread
# skip-cores 4
## Specify a number of workers to be created
## Workers are pinned to N consecutive CPU cores while skipping "skip-cores"
CPU core(s)
## and main thread's CPU core
# workers 2
## Set scheduling policy and priority of main and worker threads
## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH)
## idle (SCHED_IDLE), fifo (SCHED_FIFO), rr (SCHED_RR)
# scheduler-policy fifo
## Scheduling priority is used only for "real-time policies (fifo and rr),
## and has to be in the range of priorities supported for a particular policy
# scheduler-priority 50

## Disable mutli-segment buffers, improves performance but

# no-multi-seg
## Increase number of buffers allocated, needed only in scenarios with
## large number of interfaces and worker threads. Value is per CPU socket.
## Default is 16384

## Change hugepages allocation per-socket, needed only if there is need for
## larger number of mbufs. Default is 256M on each detected CPU socket
