yes, you can also try to execute “show memory verbose” before the failing one to see the stats…

I am able to see following error message on vppctl console. exec error: Misc After this if i execute "show int" on vppctl, all VPP configuration i did so far was lost and started with default configuration as per /etc/vpp/startup.conf. You mentioned that VPP heap is not using huge pages. In that case can I increase heap memory with startup configuration "heapsize" parameter?

What do you mean by “shared memory was unlinked” ? Which shared memory? I felt this might be because of shortage of heap memory used in VPP and might be solved with increase of huge page memory. VPP heap is not using hugepages. Regards, Balaji On Wed, Sep 6, 2017 at 7:10 PM, Damjan Marion (damarion) <damar...@cisco.com<mailto:damar...@cisco.com>> wrote: why do you need so much memory? Currently, for default number of buffers (16K per socket) VPP needs around 40MB of hugepage memory so allocating 1G will be huge waste of memory….
