Based on BT, two issues can be expected. First, a problem could occur in vconf when calling the setting getter while the system is not fully initialized. Alternatively, a deadlock could occur on the same conf when calling the setting getter after registering the changed callback. Since this issue did not occur after a reboot or subsequent routines, it is likely a timing issue due to the callback rather than an initialization issue. Therefore, the problem can be prevented by calling the setting getter before registering the changed callback. ``` crash dump (gdb) bt #0 0x0000ffff94a13524 in __GI___poll (fds=0xfffff49d3830, nfds=1, timeout=<optimized out>) at ../sysdeps/unix/sysv/linux/poll.c:41 #1 0x0000ffff938f44e8 in ??
