Hi all,
we did some additional test by setting multithread debug on FreeRadius and
executing freeradius process tracing on server

Follow the server tracing output (each crash the same output):



*select(11, [4 6 7 8 9 10], NULL, NULL, {0, 302488}) = 1 (in [8], left {0,
302488})*

*recvfrom(8, "\4y\0\251", 4, MSG_PEEK, {sa_family=AF_INET,
sin_port=htons(38662), sin_addr=inet_addr("192.168.88.151")}, [16]) = 4*

*getsockname(8, {sa_family=AF_INET, sin_port=htons(2648),
