After some time hard debugging, I think there might be a potential overrun issue in clib_pmalloc_create_shared_arena. This is the modified code: return pm->base + ((uword) pp->index << pm->def_log2_page_sz); pp->index is u32, it would wrap after 4 times creation when the page size is 1G. The overlapped va leads to very unexpected result. A patch was created for correction: https://gerrit.fd.io/r/15847 Please take a look at it. Appreciate your comments. Regards, Kingwel
