Hi, I can view thread information of radiusd process by attaching its process ID into gdb as follows
gdb -q - 19201 After that (gdb) bt #0 0x00000037ed8cc4c2 in select () from /lib64/libc.so.6 #1 0x00002aefb56dd817 in fr_event_loop (el=0x72848a0) at event.c:378 #2 0x000000000041a877 in main (argc=<value optimized out>, argv=0x3ec) at radiusd.c:398 Does it have any implication on Radius crashes that happened before?
