hi,my team is going do our own business in primary forked process, to make =
sure
business won't affect the primary, we may refork the business process many
times,
now there comes the problem:
when the first time fork the process ,it runs good, but, it recieved sig-11=
on
call rte_ip_frag_table_create after the second time fork. here is the
backtrace:
(gdb) bt
#0 0x00007fb913af4dc5 in malloc_elem_insert () from /lib/libdpdk.so
#1 0x00007fb913af5e97 in alloc_pages_on_heap () from /lib/libdpdk.so
#2 0x00007fb913af6154 in try_expand_heap () from /lib/libdpdk.so
#3 0x00007fb913af65a1 in alloc_more_mem_on_socket () from /lib/libdpdk.so
#4 0x00007fb913af6c9a in malloc_heap_alloc () from /lib/libdpdk.so
#5 0x00007fb913af84e3 in rte_malloc_socket () from /lib/libdpdk.so
#6 0x00007fb913af863f in rte_zmalloc_socket () from /lib/libdpdk.so
#7 0x00007fb913a4343f in rte_ip_frag_table_create () from /lib/libdpdk.so
does the primary do not allow malloc and free memery at forking process?
could you do me a favor? thanks
