<pre class="bz_comment_text">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
